Just filed bugs for this and a new rather severe one involving address arithmetic. Robert On Fri, Jul 24, 2009 at 1:34 AM, Evan Cheng <evan.cheng at apple.com> wrote: > Can you file a bug?

...ARMISelLowering.h. I think I have done that myself, but I recently discovered that the extra lines are intentional. Doxygen recognizes C+ + comments beginning with 3 slashes but you have to have at least 2 lines of them or doxygen will not recognize them.

...cl::init(".data.jtab")); + Is this necessary? Why not just put it in the normal data section? Also "outline" jumptable seems like a strange term. Can you think of something else?

...run these tests at the moment, but walking manually through va-arg-1.c, it's pretty clear that there's some disconnect between the register spilling that happens in LowerFORMAL_ARGUMENTS and what happens in LowerVASTART in ARMISelLowering.cpp. deep On Thu, Jun 11, 2009 at 8:45 AM, robert muth<robert at muth.org> wrote: > I wrote a few scripts to run llvm/arm against the gnu c torture test suite > which consists of  over 900 smallish tests. > > There were quite a few failures with llvm/arm which I hereby want to > report (see attached > tarball for the actual fail...

I wrote a few scripts to run llvm/arm against the gnu c torture test suite which consists of over 900 smallish tests. There were quite a few failures with llvm/arm which I hereby want to report (see attached tarball for the actual failing testsc). Most of the failures are related to vararg/stdarg. I think I saw a bug files for this but cannot find it anymore. Is somebody on this? Finally, I

Hi: This is my first patch submission. Hopefully, this is the proper the protocol. Attached is a patch for the llc ARM backend: Added mechanism to generate switch table in a data section rather than having it interleaved with the code. This is controlled by command line flags and off by default. Also, tried to document and improve the code where I modified it. Robert -------------- next part

I have been struggling with this for way too long now, so hopefully the mighty list can help: I am trying to generate a byte store instruction storing the constant value 4 at some given address in a new helper function inside ARMISelLowering.cpp I tried: SDValue Val = DAG.getConstant(4, MVT::i8); SDValue Store = DAG.getStore(chain, dl,
