Source: llvm-toolchain-7
Version: 1:7.0.1~+rc2-7
Severity: grave
LLVM violates the i386 baseline by using SSE2, which on this Pentium
III machine results in a crash when starting xorg due to an illegal
instruction:
[ 112.413] (EE)
[ 112.413] (EE) Backtrace:
[ 112.414] (EE) 0: /usr/lib/xorg/Xorg (OsLookupColor+0x122) [0x5c4a62]
[ 112.416] (EE) 1: linux-gate.so.1 (?+0x0) [0xb7fc5d68]
[ 112.420] (EE) 2: /lib/i386-linux-gnu/libLLVM-7.so.1
(_init+0x52eea) [0xae21d898]
[ 112.420] (EE)
[ 112.421] (EE) Illegal instruction at address 0xae1ca9ae
[ 112.421] (EE)
Fatal server error:
[ 112.421] (EE) Caught signal 4 (Illegal instruction). Server aborting
Reverting back to mesa 18.1.9 and thus LLVM 6 fixes the problem.
With the LLVM dev tools, the problem can be trivially reproduced:
$ llvm-config-7
Illegal instruction
$
GDB confirms that it's caused by SSE2:
(gdb) x/1i $eip
=> 0xb4fde9ae: punpcklqdq %xmm1,%xmm2

Closes: 894840 913946 914770
Changes:
llvm-toolchain-7 (1:7.0.1~+rc2-8) unstable; urgency=medium
.
* Use llvm-strip instead of binutils strip.
Two reasons:
- with clang stage2, the dbg packages were not generated
- strip fails on stretch and other ubuntu on some archives
For this, I had to silent the --enable-deterministic-archives
option (https://bugs.llvm.org/show_bug.cgi?id=39789).
Thanks to Rebecca Palmer for the idea
(Closes: #913946)
* Change the i386 base line to avoid using sse2 extension
This is more important now that llvm is built with clang
instead of gcc.
Thanks to Fanael Linithien for the patch
(Closes: #914770, #894840)
