[Darwin PowerPC] tilde fails to launch: `Program received signal EXC_BAD_INSTRUCTION, Illegal instruction/operand` #114

Open barracuda156 opened 9 months ago

barracuda156 commented 9 months ago

While it builds fine, it does not launch:

macmini:~ svacchanda$ /opt/local/bin/tilde
Illegal instruction

Confirmed both on 10.6 ppc (native) and 10.6.8 (Rosetta).

GDB gives:

At the same time no problem on 10.6 i386.

@gphalkes Any idea what goes wrong?

programmingkidx commented 7 months ago

I'm guessing the build system is having problems making a PowerPC binary on x86. Could you try building a PowerPC binary on a PowerPC Mac?

@programmingkidx I did build on ppc natively, same error. image

programmingkidx commented 7 months ago

Wow, not very many people know about the PowerPC version of Mac OS 10.6. I think it was only in beta on PowerPC. Would you be able to try on Mac OS 10.5 or on Mac OS 10.4?

If you don't want to do that could you use gdb to debug the program? Start debugging: gdb ./tilde Start tilde: run When you see the error run this command to show the instructions: disassemble $pc,+15 Provide the information you receive from gdb here. Good luck.

barracuda156 commented 7 months ago

@programmingkidx Thank you! Will do this today and update you.

P. S. My 10.5 installation is temporarily broken (needs to build gcc13, I just don’t get time to sort it there), but 10.4 is doable. Don’t use it normally, but as long as dependencies build, it should work.

Thank you for the information. Which version of gcc are you using to build tilde? Are you using the same version of gcc to build all of tilde's dependencies? Which version of ld are you using? ld -v

From the information above it looks like a data section is somehow trying to be executed. That is bad. I hope tilde can build on Mac OS 10.4. If you try it could you let us know how it goes?

Macports normally switches to newer compilers when that is required, so as long as something builds with a default compiler, the latter is used. Of immediate tilde deps, some use gcc13 (where C/C++11 or higher needed or where gcc-4.2 just fails to build a given port), while other use gcc-4.2:

Notice, this behavior will be the same for all PowerPC systems, though 10.4–10.5 gonna pick gcc7 (instead of gcc13).

I can try rebuilding all of these with gcc13 just to check.

programmingkidx commented 7 months ago

Using different versions of gcc is where my vote goes for this problem. You might want to try building tilde and its dependencies yourself from source using my directions: https://trac.macports.org/ticket/68594.

Another suggestion that comes to mind is to force using gcc7 to build everything. I think macport's has an option to do this. This page looks very help: https://trac.macports.org/wiki/UsingTheRightCompiler.

Also your ld version seems kind of low. I think it would be a good idea to upgrade it.

barracuda156 commented 7 months ago

Another suggestion that comes to mind is to force using gcc7 to build everything. I think macport's has an option to do this.

Rather blacklist *gcc-4.* and let Macports pick a newer compiler. Forcing a specific one should be generally avoided.

Also your ld version seems kind of low. I think it would be a good idea to upgrade it.

It is pretty old, but it is the best one for ppc/ppc64 at the moment. While ld-127 build and works on powerpc, it has issues. Linker should not a problem, after all it is good enough to build the current gcc, CMake and thousands of other ports.

barracuda156 commented 7 months ago

@programmingkidx Just in case, can something in those ports referred to in your #68594 ticket set -mcpu=native optflag? I mean, from the sources side; Macports build system does not add that by default.

barracuda156 commented 7 months ago

@programmingkidx Look what I found:

  1. If I build libt3config with gcc-4.2, then libt3key builds normally.

  2. If I force gcc-13 for libt3config, then libt3key does not build with either gcc:

This is probably wrong for ppc in libt3config:

typedef char t3_bool;

Bool is 4-byte, unless of course this in fact must be forced to 1-byte size.

programmingkidx commented 7 months ago

@programmingkidx Just in case, can something in those ports referred to in your #68594 ticket set -mcpu=native optflag? I mean, from the sources side; Macports build system does not add that by default.

I think you could using that flag with the CXXFLAGS and CFLAGS variables when using configure. I never used it myself.

programmingkidx commented 7 months ago

@programmingkidx Look what I found:

1. If I build `libt3config` with gcc-4.2, then `libt3key` builds normally.

2. If I force gcc-13 for `libt3config`, then `libt3key` does not build with either gcc:

Good catch. I'm wondering if gcc7 has this issue also.

barracuda156 commented 7 months ago

I think you could using that flag with the CXXFLAGS and CFLAGS variables when using configure. I never used it myself.

My concern was the opposite: we should avoid using it, at least for debugging, since it is unsafe and can cause obscure breakages. But anyway, since it is not used, this is not relevant to the case.

I'm wondering if gcc7 has this issue also.

I have a zoo of gcc here, let me try. (But if anything, gcc13 should have less bugs that gcc7. gcc7 was pretty bad in fact.)

barracuda156 commented 7 months ago

@programmingkidx Yes, both with gcc6 and gcc7 same issue.

I'm not familiar with any issues with bool on PowerPC. I also wonder why the author chose to use char as his own bool type. C99 comes with a bool type built-in.

I have a zoo of gcc here, let me try. (But if anything, gcc13 should have less bugs that gcc7. gcc7 was pretty bad in fact.)

Sorry to hear about gcc7. If it isn't good then I would skip testing it. After reading the notes for libt3widget it looks like C++11 support is required. So pretty much everything after gcc 4.8 should be fine. The key issue is building all the dependencies and tilde using the same compiler. Hopefully that will fix your issue.

barracuda156 commented 7 months ago

We should still verify on 10.5, ideally, to be sure. (I believe my gcc work robustly on 10.6, and this is the only instance of such an error which I can recall, but still, 10.6 is not the standard ppc config.)

barracuda156 commented 7 months ago

@programmingkidx

I'm not familiar with any issues with bool on PowerPC

32-bit ABI uses 4-byte bool, unlike pretty much everything else, including macOS ppc64 ABI (there bool is standard 1-byte). This may break something when it is not considered, and normally it is not. Not just alignments, but sfinae, suddenly, etc.

If it isn't good then I would skip testing it.

I did not mean to discourage testing, since gcc7 is what 10.4–10.5 got at the moment by default, FWIW. I do have specific cases in mind when I say it had issues, but it is far from being broken – it still should work fine for most of the stuff.

The key issue is building all the dependencies and tilde using the same compiler.

Well, since it needs C++11, gcc-4.2 is out of question (some dependencies cannot be built with it), while with gcc13 I cannot build both libt3config and libt3key :) I should try on 10.4, and thought to do that today, but forgot to take a power adapter for the external drive with Tiger. Will return to this.

programmingkidx commented 7 months ago

I was watching this video: https://www.youtube.com/watch?v=gS-_8kl_OpA. It is titled "So broken: GNU binutils regression breaks GCC PowerPC. You can't make this waste of time up :-/". It made me wonder, did you update your binutils?

barracuda156 commented 7 months ago

Looks like Macports has cctools 949.0.1. Generally speaking, it works. Of course we still cannot exclude a) a genuine compiler bug and b) peculiarity of 10.6 ppc.

As for the latter, however, I recall that I built tilde on 10.6 i386 which is the same developer build and which uses the same gcc13, like my powerpc system, and there is worked normally. At the same time on 10.6.8 Rosetta it failed (and 10.6.8 is a standard release with standard gcc). So I tend to think that this is not an OS bug, but specifically something does not work on ppc (or big-endian in general).

programmingkidx commented 7 months ago

I didn't think about the endianness of the CPU being a possible cause. Bit operations tend to be sensitive to it. I haven't gone thru all of tilde's source code so it is possible there is something that depends on a little-endian CPU.

With your already built tilde could you have dyld print all the libraries it tries to load for it? I think one of the dependencies is to blame for tilde's failure. To find this out we have to find out where in the loading cycle things fail.

Directions:

I had AI look at your stack trace. This is what it said:

The crash you’re seeing is due to an EXC_BAD_INSTRUCTION error. This error generally means that there was an assertion failure in your code1.

The stack trace shows the sequence of function calls leading up to the crash. Here’s a brief explanation of some of the functions involved:

[dyld_stub_uc_is_general_category_withtable: This function is a stub, which is a small piece of code used as a placeholder or substitute for another programming functionality](https://stackoverflow.com/questions/8825537/mach-o-symbol-stubs-ios)[2](https://stackoverflow.com/questions/8825537/mach-o-symbol-stubs-ios).

The exact cause of the crash would depend on the specifics of your code and what it’s trying to do when the crash occurs. It could be due to an issue with dynamic linking, a problem with initialization of some component, or a variety of other reasons. You might need to debug your code to find out the exact cause. If you’re using assertions in your code, you might want to check if those are being triggered incorrectly. If you’re dynamically loading code or libraries, you might want to verify that all dependencies are correctly installed and accessible.

uc_is_general_category_withtable comes from libunistring.

programmingkidx commented 7 months ago

Ok lets test libunistring.

This program uses libunistring to make an uppercase string:

#include <stdio.h>
#include <stdlib.h>
#include <unistr.h>
#include <unictype.h>

int main() {
    uint8_t input[] = "Hello, World!";
    uint8_t output[100];
    size_t length;

    // Convert the input string to uppercase using libunistring
    for (length = 0; input[length] != '\0'; length++) {
        uint32_t ch;
        u8_mbtouc(&ch, &input[length], 1);
        ch = uc_toupper(ch);
        u8_uctomb(&output[length], ch, 1);
    }
    output[length] = '\0';

    printf("%s\n", output);

    return 0;
}

Try to run this program on your system. Copy this source code into a file called main.c. Then run this command to build the program: gcc -o test main.c -L/opt/local/lib -lunistring -I/opt/local/include/ Then run the program test: ./test You should see this output if successful: HELLO, WORLD!

Note: the paths for the libaries and include files might be different on your computer. The find command could help you here.

@programmingkidx I will do Tiger testing today, but here tilde runs on 10.6 i386 (10a190). Notice, it uses identical gcc13 (with a patch for 10a190), it also builds some dependencies with gcc-4.2, however there is no breakage. This does not rule out ppc-specific bug in either gcc or binutils, but it rules out, IMO, libstdc++ incompatibility, 10.6 SDK issues and possible general bugs in gcc13.

Illegal instruction

@programmingkidx So it is also broken on Tiger:

36-64:~ svacchanda$ tilde Illegal instruction

So tilde is always broken on PowerPC whether it is in Rosetta, Mac OS 10.4, or Mac OS 10.6. The problem is always EXC_BAD_INSTRUCTION.

The problem before was with libunistring. Now it is with libt3widget. I did a grep search for "resultbuf" in libt3widget. Nothing was found. I am not sure where it is coming from. I then looked for the key_bindings_t in libt3widget. I did find it mentioned in src/key_binding.h. The thing is this is a header file and they are usually used for just defining constants and function prototypes. This file has all the function definitions. But this isn't illegal so I don't know what exactly is wrong with this code.

Here is what I found:

class T3_WIDGET_API key_bindings_base_t {
 public:
  virtual ~key_bindings_base_t();
  virtual size_t names_size() const = 0;
  virtual const std::string &names(size_t idx) const = 0;
  virtual bool bind_key(key_t key, const std::string &name) = 0;
};

template <typename T>
class T3_WIDGET_API key_bindings_t : public key_bindings_base_t {
 public:
  struct param_t {
    T action;
    std::string name;
    std::initializer_list<key_t> bound_keys;
  };

  key_bindings_t(std::initializer_list<param_t> actions) {
    for (const param_t &action : actions) {
      name_mapping[action.name] = action.action;
      for (key_t key : action.bound_keys) {
        if (key >= 0) {
          key_bindings[key] = action.action;
        }
      }
    }
  }
  key_bindings_t() {}

I'm not great at C++ so I'm not sure if there are any problems here. One thought I had was about the compiler being used to build tilde. I and pretty much everyone else who installs tilde on Mac OS is probably going to be using clang++. You are using gcc. I was going to suggest trying clang but I don't it would work on PowerPC very well. Then again you said you were able to build and run tilde successfully on Mac 10.6 x86. You used gcc13. So I guess my vote goes with binutils being the problem.

Another thought I had was what if someone tried to build tilde on Linux running on PowerPC? Would that work or have the same problems? I don't expect you to install Linux, but if you did and tried to install tilde, please post your results. If it fails on Linux with gcc13 or another gcc version then it might indicate an issue with binutils. On Linux you would have access to clang. This does not use GNU binutils so we might see some success there.

No version of clang works or worked on any macOS PowerPC. We have flexibility with gcc versions, but no clangs.

@kencu Ken, maybe you could try building it on Debian and see if it runs normally or crashes?

barracuda156 commented 7 months ago

@programmingkidx I wonder if it is also broken on 10.4–10.5 Intel. If the issue is related to dyld_stub_binder, that was not supported until 10.6 and is not supported on 10.6 ppc (and in Rosetta either).

Great, please let me know! I would like to fix this, and it seems helpful to know if older Intel works or not. That gonna narrow down possible causes of the problem.

programmingkidx commented 7 months ago

Well I currently ran into a problem. While trying to install software using MacPorts in my Mac OS 10.5 x86 vm I saw an error with M4. I did report the issue but the ticket was closed for being a duplicate of this ticket: https://trac.macports.org/ticket/62994. Would you know a way to avoid having to install M4 thru MacPort? It is a dependency of a lot of software. I was able to make is successfully outside of MacPorts. Unfortunately I don't know of a way to tell MacPorts to use my own M4.

barracuda156 commented 7 months ago

Does that help? https://trac.macports.org/ticket/62994#comment:94

@programmingkidx This should fix the issue with a failing m4 on Leopard: https://github.com/macports/macports-ports/pull/23426

I just made it past the m4 issue. I am still trying to install Tilde on Mac OS 10.5 x86. There is a lot of prerequisites I have to go thru first, so it will take a while.

@programmingkidx Can we somehow avoid using libtool and link instead normally with the compiler?

programmingkidx commented 2 months ago

A thought did come to my mind about forking all the packages that make up tilde, removing all the newer C++ features, and making them compatible with Mac OS 10.5. I see a lot of advantages to doing things this way.

As for avoiding libtool, that sounds like a good idea.

barracuda156 commented 2 months ago

Why I asked about libtool: I had a case recently when libtool added an unsupported symbol on ppc (infamous dyld stub helper), but simply dropping libtool part from linking command fixed it. Not necessarily related to the present case, but may be worth trying.

programmingkidx commented 2 months ago

Is this a problem with Apple's libtool or with GNU's libtool?

barracuda156 commented 2 months ago

Is this a problem with Apple's libtool or with GNU's libtool?

The code explicitly allows only GNU one. So the port uses that.

Won’t be surprised if it has a bug, perhaps never tested in a decade…

programmingkidx commented 2 months ago

Would you know which version of GNU's libtool is the problem? hint: glibtool --version

barracuda156 commented 2 months ago

2.4.7

https://ports.macports.org/port/libtool

(But if the bug is here, it should be something rather subtle, otherwise everything would be broken which uses GNU libtool, which is not the case, of course.)
