Yes, thanks, I hadn't noticed the -strip-debug-declare. Incidentally I only "see" the failures because some "TEST-FAIL" messages whizz up and off the screen. The actual "make

In lib/CodeGen/SelectionDAG/TargetLowering.cpp there are some functions magic() and magicu() that support optimising division by a constant. I'd like to use these functions in an LLVM FunctionPass that I'm working on. The attached patch moves these functions out of TargetLowering.cpp and into the APInt class, so that I can reuse them in my pass. What do you think? It looks to me like

Unfortunately Cygwin is not in our release criteria. I'd like to have a buildbot running (if there is not one already) and then get someone to qualify it for the

I'm trying to cross-compile LLVM with build=, host=target=. I'm using the following packages from Debian lenny: mingw32 4.2.1.dfsg-1 mingw32-binutils 2.18.50-20080109-1 mingw32-runtime 3.13-1 The first problem I hit was when I configured with CC, CXX, AR and RANLIB set to mingw cross-tools, but forgot to specify NM as well. This resulted in a load of warnings that scrolled off the

I've always found the name ComputeMaskedBits a bit unintuitive, and since r154011 it's even worse because there is no masking going on whatsoever: http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20120402/140280.html Is there any appetite for a global rename to ComputeKnownBits? Or any other better names? Thanks, Jay.

Hi, If I configure llvm-gcc 2.6 with --target=mips or --target=mips-elf, I get: c++ -c -g -O2 -DIN_GCC -DCROSS_DIRECTORY_STRUCTURE -W -Wall -Wwrite-strings -pedantic -Wno-long-long -Wno-variadic-macros -Wmissing-format-attribute -fno-common -DHAVE_CONFIG_H -Wno-unused -DTARGET_NAME=\"mips-elf\" -frandom-seed=0 -I. -I. -I/home/foad/toolchain/llvm/llvm-gcc/gcc

I'm trying to run some of the test suite using the instructions here: http://llvm.org/docs/TestingGuide.html#quicktestsuite I've built llvm myself, but I'm using pre-built binaries of llvm-gcc (from http://llvm.org/prereleases/2.5/llvm-gcc4.2-2.5-x86-linux-RHEL4.tar.gz). Here's what happens: foad at debian:~/svn/llvm-project/test-suite/trunk$ ./configure

Hi, From v3.0.0 onwards the hash function implemented by Rsync was changed from MD4 to MD5 (http://rsync.samba.org/ftp/rsync/src/rsync-3.0.0-NEWS). My understanding is that MD5 is a more secure, slower version of MD4 but I am not convinced that the added security of MD5 would alone have merited the change from MD4 (particularly since MD4 is ~30% faster than MD5). I wonder if I am missing other

(Resending with the correct mailing list address.) Hi, Currently test/asan/TestCases/alloca_vla_interact.cc is XFAILed for powerpc64. I've had a look at why it doesn't work. I think the only problem is in the call to __asan_allocas_unpoison that is inserted at the end of the "for" loop (just before a stackrestore instruction). The call function is created something like this

Hi, I've just tried to run the test-suite, for the first time in ages.
