Hi all, Here's a proposed patch for exception handling on Darwin. Basically, it spits out a global stub for the personality functions, and uses this: .long L____gxx_personality_v0$non_lazy_ptr-. instead of doing ".set ..." magic. Comments? -bw

Hello, Bill > Comments? I don't personally like this patch. It seems, that emitted data encoding is linker (=subtarget) specific. For example, gcc uses three different data encodings to emit dwarf data on darwin. I think we should introduce subtarget hooks for encoding selection of data being emitted (there is already one: needSet / *AbsoluteOffsets etc). Also "generic" function

Here are my test results for the 2.2 prerelease. Built objDir == srcDir, release, and with the pre-built LLVM-GCC binary. "make test" results: === Summary === # of expected passes 2533 # of expected failures 6 -bw -------------- next part -------------- An embedded and charset-unspecified text was scrubbed...

Hi all, This is a (very) rough patch to fix building LLVM with exceptions on PPC Darwin. Basically, it puts the burden of adding the "--enable-eh" on the specific target, which is where I think it should go. If this is okay, then I can clean the patch up and submit it. -bw Index: gcc/llvm-backend.cpp =================================================================== ---

Is the flag_objc_abi variable available on non-Darwin platforms in llvm-gcc? I want to use it in llvm-backend.cpp to conditionalize a test. But I don't want to break Linux, Ada, Fortran, etc. -bw
