I just got this error message from the GNU assembler: Error: alignment too large: 15 assumed Which made me laugh at first. The corresponding input line was: .align 16 Apparently what's going on here is that ".align 16" is ambiguous: on some architectures it means ".balign 16", and on some it means ".p2align 16", which would mean ".balign 65536" if it were allowed. See: http://ftp.gnu.org/pub/old-gnu/Manuals/gas-2.9.1/html_node/as_68.html I'm not sure what the best way is to fix this. If LLVM wants to support other assemblers presumably...

Hi, I've come across some problems with the assembly version of the ELFNOTE macro currently in -mm. (in x86-put-note-sections-into-a-pt_note-segment-in-vmlinux.patch) The first is that older gas does not support :varargs in .macro definitions (in my testing 2.17 does while 2.15 does not, I don't know when it became supported). The Changes file says binutils >= 2.12 so I think we need

hi, i was trying to enable the mmx code on mac os x. to get to that point one has to replace some inline assembler code: .balign 16 -> .p2align 4 and replace .rept .. .endr with #defines. but to makes things more complicated apple's GAS does not support movsx instructions and thus the following line does not work: " movsx %%di, %%edi \n\t" [ more details at https://trac.xiph.org/browser/trunk/...
