Hi, guys, I compiled a subroutine with -O2, and llvm backend produced codes like: ################################################################## LBB0_32: ... R31 = -1 R20 = R31 * R20; .... bnz R2, LBB0_34 LBB0_31: ... b LBB0_34 LBB0_33: # weird basic block? R20 = R5 LBB0_34: .... ################################################################## Wrong answer is produced when executing bove codes. LBB0_33 is not used as destination basic block for any b...

Hi Yang, > bnz R2, LBB0_34 > > I do not have any clue what happens when compiling with -O2. > Can someone make a suggestion? Is the "bnz" instruction marked "isBarrier" in your TableGen files? If so, that would mean LLVM considers fallthrough impossible and decides it can move LBB0_...

Greetings, LLVM devs, For the past few weeks, I have been putting together a 6502 backend for LLVM. The 6502 and its derivatives, of course, have powered countless microcomputers, game consoles and arcade machines over the past 40 years. The backend is just an experimental hobby project right now. The code is available here: <https://github.com/beholdnec/llvm-m6502>. This branch introduces

I have updated the klibc patchset based on feedback received. In particular, the patchset has been reorganized so as not to break git-bisect. Additionally, this updates the patch base to 2.6.17-git12 (d38b69689c349f35502b92e20dafb30c62d49d63) and klibc 1.4.8; the main difference on the klibc side is removal of obsolete code.
