[LLVMdev] LLVM and little-endian 32-bit MIPS code generation
Hi,
We have tried and generate assembly code for very simple test C code.
But, binutils-2.5.2 (simplesim-3.0) cannot handle the produced assembly code
with the following complaints. Could you advise which version of bitutils
that we need to use for mips code with LLVM with Clang? Thanks,
$ GCC addr01.s

Something released in the last 10 years maybe? Just download something recent from gnu.org and you should be fine.

[LLVMdev] LLVM and little-endian 32-bit MIPS code generation
It will produce little-endian code if you replace "mips" with "mipsel".
1. clang -ccc-host-triple mipsel-unknown-linux -ccc-clang-archs mipsel -O3
-S -emit-llvm foo.c -o foo.ll
2. llc -march=mipsel -mcpu=4ke foo.ll -o foo.s (the -march option is
redundant)
If you do not specify the target cpu with -mcpu, by default it will generate
code for Mips1, which has not been tested as

[LLVMdev] LLVM and little-endian 32-bit MIPS code generation
We are trying to use LLVM (Clang as the C frontend) to generate code for
32-bit MIPS (little-endian)l, which can run on simplescalar 3.0
sslittle-na-sstrix platform. Can you advise what would be the right way to
use the LLVM compiler infrastructure?
The following is the one I used, but it appears that it produce the code in
big-endian (and I wonder whether the calling convention is right.) To
