Hi All, I have a fix to this bug ( https://bugs.r-project.org/bugzilla3/show_bug.cgi?id=16454) and would like to submit a patch to the bug report on Bugzilla. I'd also like to start going through some of the other Windows-specific issues and start fixing those. The bug submission instructions indicate that I should ask here for a Bugzilla account. Is that still the correct procedure? Thanks!

Thanks for the link!

Hi all, I'm using LLVM 3.0, for which I've filed following bug http://llvm.org/bugs/show_bug.cgi?id=12130<https://webmail-eu.st.com/owa/redir.aspx?C=f2882890c0064e71ba4c8238dc7fd399&URL=http%3a%2f%2fllvm.org%2fbugs%2fshow_bug.cgi%3fid%3d12130> . I'm trying to solve this problem by myself digging into LLVM sources. It seems that problem that I'm experiencing is related to presence or absence of NSW attribute on a 'mul'. Considering following code: define void @t2(double* %x) { L.entry: %...

Hello, I'd like to implement the gnu attribute "scalar_storage_order" to mark structs with non-native endianness. My rational is working on network protocols over little endian architecture (for instance: RiscV). An old bug is open on this issue here: https://bugs.llvm.org/show_bug.cgi?id=35293 I'd like to discuss the possible ways to implement this. The GCC implementation is

Hello folks, I've recently been looking at the generated code for a few functions in Chromium while investigating crashes, and I came across a curious pattern. A smallish repro case is available at https://godbolt.org/z/Dsu1WI . In that case, the function Assembler::emit_arith receives a struct (Operand) by value and passes it by value to another function. That struct is 8 bytes long, so the

This is a bug found by internal compiler bootstrap, and possibly it is the root cause of https://bugs.llvm.org/show_bug.cgi?id=33652 and https://bugs.llvm.org/show_bug.cgi?id=33626. Here is the testcase 1.c. The original code is at MemorySSA.cpp:586 for rL307764. ------------------------- 1.c --------------------------- long a, c, d, e, f, m, cnt, i_hasval; volatile long b; void goo(long); void

Greetings, I'm an LLVM newcomer interested in participating in the next GSoC under the project "Improve parallelism-aware analyses and optimizations". I've already read "Compiler Optimizations for OpenMP" and "Compiler Optimizations for Parallel Programs" both by Doerfert and Finkel. Also, I've watched their two LLVM meeting developers conferences
