Description Nicholas Haggin 2010-04-30 16:14:08 UTC
Description of problem:

When invoked without specifying word size (-m32 or -m64), gcc appears to default to compiling 64-bit code and then invoking the assembler in 32-bit mode.

Version-Release number of selected component (if applicable):


How reproducible:

Compile any C source file.
Actual results:

[user@localhost ~]$ gcc hello.c
/tmp/ccYn3Uv7.s: Assembler messages:
/tmp/ccYn3Uv7.s:17: Error: junk at end of line, first unrecognized character is `@'
/tmp/ccYn3Uv7.s:29: Error: syntax error; found `@' but expected `('
/tmp/ccYn3Uv7.s:29: Error: junk at end of line: `@toc(2)'
[user@localhost ~]$ 

Expected results:

[user@localhost ~]$ gcc hello.c
[user@localhost ~]$ 

Additional info:

The machine in question is a Mac Xserve G5. Originally, the ppc64-architecture packages for GCC and binutils were installed; later, the 64-bit packages were removed and the 32-bit packages were installed. A machine installed from scratch with only the 32-bit packages works correctly, making me suspect a package configuration bug of some sort.

Comment 1 Jakub Jelinek 2010-04-30 16:21:33 UTC
If you have gcc.ppc but binutils.ppc64 installed (or gcc.ppc64 and binutils.ppc), that's just a user error.  Don't do that.
