[LLVMdev] [PATCH] Apply Thumb2 ROR optimization only when Thumb2 is supported
...ou're absolutely right, that pattern should definitely have an "only-in-Thumb2" predicate attached.
Do you have commit access? Also, if you have a reduced test case, that would be awesome, but the patch is correct as-is even if not.

[LLVMdev] [PATCH] Apply Thumb2 ROR optimization only when Thumb2 is supported
I've been playing around with using LLVM on one of our projects, which
runs on an arm1176jzf-s processor. When compiling for Thumb, a couple
of the generated assembly files end up with a 'ror.w' instruction,
which is a Thumb2 instruction. Since arm1176jzf-s doesn't support
Thumb2, the assembler then turns around and barfs on it.
I don't have any experience with this

[LLVMdev] LLVM compile speed significantly slower than GCC (w/ test case)
Thanks, Matt. This is great information. Sounds like Chandler is looking into the details of what's going on.

[LLVMdev] Problem with __inline keyword
I'm attempting to use clang/llvm to compile some legacy C code, and am
running into a strange issue. There are several functions in my
codebase which make use of the __inline keyword, but do not include
the customary static keyword along with it. When I compile these
files, the generated code appears not to have any of the function
definitions in it--just undefined references to external

[LLVMdev] LLVM compile speed significantly slower than GCC (w/ test case)
I've been doing some profiling of LLVM on our codebase, to see how it
stacks up to the existing GCC build that we do. The primary thing I'm
focusing on at the moment is build speed, and in this regard LLVM
seems to be pretty all over the map. On some files it seems to go
quite a bit faster than GCC, and on others it's slower, leading to an
aggregate build time for our repository
