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/theora/lib/ x86_32/dsp_mmx.c#L443 ] if...

Hello Kevin, I thinking about this, but there are some problems: 1) Differrent interpretation of $[:number:] in macro body: source: .macro test par1 movl $0, %eax .endm test %ebx translated to: original llvm => movl %ebx, %eax with patch => movl $0, %ebx 2) Different parsing of space in macro parameters: source: test2 a + b,c parsed as: original llvm => macro test2 with two

Hello, This series has been split into two patches, one for arm and one for x86. I figured that this was easier than doing it as a single combined patch, especially as the changes are functionally independent. x86 has been boot tested, but arm has not even been compile tested as I lack a suitable cross compiler. However, the changes are just text replacement, so I dont expect any issues. The

Hi useRs - I was wondering if anyone out there can tell me where to find R-code to do mixes of tables and graphics. I am thinking of something similar to this: http://yost.com/information-design/powerpoint-corrupts/ or like the excel routines people are demonstrating: http://infosthetics.com/archives/2006/08/excel_in_cell_graphing.html My aim is to provide small graphics to illustrate
