...ow I'm running into a requirement to do this again: while it's much less crashy than it was, I still can't seem to persuade the JIT to generate hard-float code. This is with LLVM 3.3, 3.4 and 3.5. I'm using MCJIT (although I've tried without, as well), and I've tried setting FloatABI to HardFloat. Does anyone know if this is actually working yet? If so, are there any examples of how to do this successfully? -- ┌─── ｄｇ＠ｃｏｗｌａｒｋ．ｃｏｍ ───── http://www.cowlark.com ───── │ "Feminism encourages women to leave their husbands, kill their │ children, practice withcraft, destroy ca...

Targetting the raspberry pi, what triple/flags should I set? I tried triple: armv4t-unknown-linux-gnueabi and ld fails with: a.out uses VFP register arguments if i set hardfloat (using optdata.FloatABIType = FloatABI::Hard), ld fails with an assertion: 2.22 assertion fail ../../bfd/elf32-arm.c:11477 what am I missing?

Hi David, For ARM, you will need to use the MCJIT ExecutionEngine as the legacy one is broken for ARM. (call EngineBuilder::setUseMCJIT()). When creating your TargetOptions, setting FloatABIType to FloatABI::Hard should trigger codegen for the correct ABI. Amara

Both Clang/LLVM 3.4 -> Clang/LLVM 3.5 And i will also try using MCJIT. 2014-09-17 18:56 GMT+06:00 Anton Smirnov <dev at antonsmirnov.name>: > Hi, Tim. > > I've used Clang 3.4 final release and now i'm going to test it with 3.5 > release (since i've read about arm64 improvements). > I will report my results. > > BTW, is it possible to get smth like
