Extended Description

Trying to build ruby-2.3.0 with clang 3.9.0 (trunk 267338). So far, I've been unsucessful:

Clang was compiled with cmake options which can be found at:

https://github.com/elkrejzi/system-management/blob/master/bootstrap/039-llvm#L13

It was compiled with GNU GCC version 6.0.1 20160421 (prerelease).

Ruby was compiled with ./configure --prefix=/usr --disable-static --enable-shared --disable-install-capi, while also using CFLAGS="-march=skylake -fomit-frame-pointer -Os -pipe" and clang as a compiler.

clang 3.8.0 works fine (with addition of -mno-avx512f to CFLAGS because 3.8 has -march=skylake which targets AVX-512 systems which this CPU doesn't have).

Mentioned files are attached. Let me know if you need more info

Fixed in r267551.

Hi,

I bumped into exact same issue with setjmp a couple of days ago. The fix has already been submitted to the Phabricator (http://reviews.llvm.org/D19409), so I'm just waiting for it to be reviewed.

DimitryAndric commented 8 years ago

Andrey, in r261429 you enabled the LEA optimization pass by default, can you please have a look?

DimitryAndric commented 8 years ago

Minimized test case is just one line:

x0() { __builtin_setjmp(1); }

To reproduce the bug, compile with:

clang -cc1 -triple x86_64-unknown-linux-gnu -emit-obj -Os -w testcase.c

The -Os option is relevant, -O1 or -O2 do not trigger the bug.

DimitryAndric commented 8 years ago

Reproduces with trunk r266775. The emitted error is:

Invalid address displacement operand UNREACHABLE executed at /share/dim/src/llvm/trunk/lib/Target/X86/X86OptimizeLEAs.cpp:150!
