assert when using -Os

[sherpya]

I've reduced the testcase:

int func1(void)
{
        int result;

        result = func2(0, 0, 0, 0);
        if (result != 0)
                return result;

        result = func2(0, 0, 0, 0);
        return 0;
}

compile with ppu-gcc -Os testcase.c I get: testcase.c: In function 'func1': testcase.c:11:1: internal compiler error: in rs6000_savres_routine_name, at config/rs6000/rs6000.c:18375

I've added a fix from shagkur to gcc, try rebuilding the toolchain with this new patch.

[sherpya]

ok the patch works fine, I suggest you to do dos2unix on the patch since there are spurious \r

I was building git://github.com/grafchokolo/psgroove.git I think you can check it, since it does not resolve some symbols and some should be somehow in the free sdk (in psl1ght)

memcpy and memset: I dunno why it does not picks gcc builtins, I think because -Tldscript.ld -nostartfiles -nostdlib -nodefaultlibs

the other ones are lv1_xxxxx

I have a relatively fast linux box to try changes, I would be glad to help with some test

If you add --no-builtin to CFLAGS you can eliminate some of the errors.

the problem is all missing symbols are instead made in asm, for some reason the compiler mangles symbols with a dot, while the asm macro declaration is without the dot, adding the dot in the macro it works, so what is the correct mangling for symbols ? none or dot?

If you edit ppc_asm.h and change it to:

#define _GLOBAL(name)                                   \
        .section ".text";                                            \
        .align 2 ;                                                      \
        .global .name;                                             \
        .type name,@function;                                \
.name:                                                                 \

Basically putting a '.' in front of both 'name' locations. Does that work?

[sherpya]

I've also added . on .type line

[ooPo]

Did this work for you?

[sherpya]

in ppc_asm.h I have

#define _GLOBAL(name)                           \
    .section ".text";                           \
    .align 2 ;                                  \
    .globl name;                                \
    .type name,@function;                       \
name:                                           \

I've changed it in:

#define _GLOBAL(name)                           \
    .section ".text";                           \
    .align 2 ;                                  \
    .globl .name;                               \
    .type .name,@function;                      \
.name:                                          \

and it link correcly,I've noticed also while compiling others sources problems with the dot mangle, there is a reason for the dot?

[ooPo]

I suspect that something has changed recently in the toolchain and that something is mangling by default where it hadn't before. There's probably a flag you could use to reverse the behavior but I'm not sure what it would be.

[ooPo]

Is this issue still a problem?
