Bug 199651 – sys-devel/gcc-4.1.2 fails to compile (with power3 profile from 2007.1)

• Product: Gentoo Linux
• Status: VERIFIED UPSTREAM

[Description Markus Rothe (RETIRED) 2007-11-19 13:40:24 UTC]

Hello,

I have mentioned this to tgall yesterday and he told me to recompile glibc. Unfortunately this didn't fixed it.

The problem is that sys-devel/gcc-4.1.2 fails to compile:

{standard input}: Assembler messages:
{standard input}:85: Warning: Unary operator - ignored because bad operand follows
{standard input}:85: Warning: zero assumed for missing expression
{standard input}:86: Error: Unrecognized opcode: `bi'
{standard input}:96: Error: Unrecognized opcode: `bi'
{standard input}:1199: Error: unassigned file number 2


looking a the asm file created with -save-temps it looks like the bi is garbage at that position. (I'll attach the temp file)

libgcc2.s (comes from -save-temps)

[Comment 3 Markus Rothe (RETIRED) 2007-11-20 15:50:40 UTC]

removing -mcpu=power3 -mtune=power3 from CFLAGS fixed the problem for me.

[Comment 4 Tom Gall (RETIRED) 2008-01-17 18:27:22 UTC]

for later versions of gcc this is fixed. For the older profiles it's an issue. I'll remove and we'll target a new minimal gcc version for 2008.0 where this isn't a problem.

Regards,

Tom
