For ignore-undefined-symbols.s, the simplest fix ought to be to have the llvm-mc RUN line take the source from <stdin>: # RUN: llvm-mc –filetype=obj –triple=x86_64-pc-linux %s –o %t.o –g becomes # RUN: llvm-mc –filetype=obj –triple=x86_64-pc-linux < %s –o %t.o –g But in this case, llvm-symbolizer still prints the file as $CWD/<stdin> which seems like its own separate bug. --paulr

Hi all, I am working on an llvm backend for a processor with a relative simple instruction set. For small loops, the code that is produced depends heavily on how the loop is specified: The less information we provide to clang, the better the loop code becomes... Any idea how I can learn llvm that we don't have load/store instructions with register index, so that it is more efficient to

I am furiously trying to find what I am looking for in Pickaxe book and not finding it. I''m getting some values back from a posted form and I need to get the ''id'' number off the backend. The ''String'' will always come back to me as... Some_name\r\n123 where 123 is actually the id number which I need to execute the find. The reason they are coming back

Hi Got a column named ''sku'' in a table named ''product'' <%= product.sku %> ...looks like this.... ''1234_56'' These last two chars (56) are an audio Track number. I ultimately want to display: Track <%= product.sku %> I can isolate the first part with /\d+\_/ = 1234_ But can''t figure out how to get the last two

Hello. I'm having trouble with the latest patch for Cities XL 2011 (Patch_1.5.0.723_1.5.0.725.exe). The unpatched version of the game runs without issue. The patch installs fine, but then when running the game it immediately crashes to the desktop with the "deficiency in wine" error. Currently I'm using WINE 1.2.2 (I have also tried 1.3.14 & 1.3.16) in openSUSE 11.4 64

I'm using rsync-2.5.7-2 on an updated Fedora Core 1 athlon system. The -vn option lists all files to be copied or deleted, including symlinks, but it does not appear to list empty directories to be copied, even tough it copies them. It does list empty directories to be deleted. The -v option does list and copy empty directories. -v should behave the same in both instances, and the desired

Hi all, I have problem with specifying complex patterns in PPC Isel backend. I would like to fetch few instructions into one like that: def MatchPAT1 : Pat<(or (or (shl GPRC:$rA, (i32 imm:$imm24)), (and (shl GPRC:$rA, (i32 imm:$imm8)), 0xFF0000) ), (or (srl GPRC:$rA, (i32 imm:$imm24)), (and (shl GPRC:$rA, (i32 imm:$imm8)),0xFF00) )), (myinstr GPRC:$rA)>; That pattern

Hi Edwin, I ran into two problems. 1.
