The attached .ll files seem equivalent, but the resulting asm from 'opt-fail.ll' causes a crash to webkit. I suspect the usage of registers is wrong, can someone take a look ? $ llc opt-pass.ll -o - .section __TEXT,__text,regular,pure_instructions .globl __ZN7WebCore6kolos1ERiS0_PKNS_20RenderBoxModelObjectEPNS_10StyleImageE .align 4, 0x90

Yes. It's not immediately obvious whether it's in the opt or llc, though. Chris was doing work involving <2...

If I use the jump threading pass on the attached IR: $ opt before.ll -jump-threading -o - | llvm-dis -o after.ll a big chunk gets removed, a chunk that is actually necessary.

The difference is that there is a shift right after the multiply, before the divide. In IR, th...

Hi, I've attached 2 .ll files which are supposed to be equivalent but 'unopt-fail.ll' causes a crash in webkit's test suite while 'unopt-pass.ll' does not. I can't give more details about the crash, when I run the crashing test it in isolation it passes, when I run the full suite it crashes; it boggles the mind. Below I provide the optimized asm that is produced from

Ping - we've hit another of these (propagating Diagnostic::OwnsDiagClient into other places) in http://llvm.org/viewvc/llvm-project?view=revision&revision=221884 Any ideas how we should be tackling this overall? I'm not entirely convinced these are fixable by design and I think we might honestly want a conditional-ownership smart pointer... But I'm happy to hold off on that a
