Klibc FTBFS with '-mno-odd-spreg' on mips32(el) platforms, As it try to save/restore odd-number FPR. Indeed no other architectures save/restore FPR at all. It shouldn't be needed. --- usr/klibc/arch/mips/setjmp.S | 24 ------------------------ 1 file changed, 24 deletions(-) diff --git a/usr/klibc/arch/mips/setjmp.S b/usr/klibc/arch/mips/setjmp.S index 68eed19..21e4115 100644 ---

Any idea about it? It may be a serious problem, as some distributions are using FPXX by default.

Hi, I noticed that klibc started crashing on 64-bit MIPS and in my quest to fix the bug I got a bit carried away and fixed a few other things as well. Here are various miscellaneous MIPS patches, although the first patch is the important one. Thanks, James *** BLURB HERE *** James Cowgill (5): mips64: compile with -mno-abicalls mips: use -Ttext-segment when linking shared library

I am having trouble trying to enable post RA scheduler for the Mips backend. This is the bit code of the function I am compiling: (gdb) p MF.Fn->dump() define void @PointToHPoint(%struct.HPointStruct* noalias sret %agg.result, %struct.ObjPointStruct* byval %P) nounwind { entry: %res = alloca %struct.HPointStruct, align 8 %x2 = bitcast %struct.ObjPointStruct* %P to double* %0 = load

I filed a bug report (Bug 12205). Please take a look when you have time. Per your suggestion, I also attached a patch which attaches to load or store nodes a machinepointerinfo that points to a stack frame object when it can infer they are actually reading from or writing to the stack. The test that was failing passes if I apply this patch, but I doubt this is the right approach, because this

Thank you for your suggestions. I implemented the first approach (provided the byval argument and offset to MachinePointerInfo) and it seems to have fixed the instruction ordering problem. It was a lot simpler than initially expected. In this particular case, is the user responsible for providing alias information to MachinePointerInfo to guarantee instructions are emitted in the correct order?

I'm just passing this patch on to the list as I know Brian is busy and I had proded him to file the bug report. http://llvm.org/bugs/show_bug.cgi?id=14721 "binutils on OpenBSD is quite old, which causes the build on mips64el to fail on MipsJITInfo.cpp - it complains of illegal operands. The attachment patches it so that it will build. All the patch does is replace the register aliases

> So in summary, each step is ABI compatible with the previous step. The linker will ensure that the end-user doesn't try to do the second step before the first step is finished since it will refuse to link a binary that contains both O32 and O32+fp64. It will produce an O32 binary given a combination of O32+fpxx, and similarly a O32+fp64 binary given a combination O32+fpxx and O32+fp64.

Hi All, In SVN head, MipsISelDAGToDAG.cpp has the following optimization: // Operand is a result from an ADD. if (Addr.getOpcode() == ISD::ADD) { // When loading from constant pools, load the lower address part in // the instruction itself. Example, instead of: // lui $2, %hi($CPI1_0) // addiu $2, $2, %lo($CPI1_0) // lwc1 $f0, 0($2) // Generate: //

Why are you reverting patches for any area that you have no authorization for ? No build was broken. This patch is fine. I am authorized to check in to the Mips area and Daniel is the maintainer for that area.
