Hello, I’m looking for the best approach which would allow for marking given LLVM IR instruction during IR custom pass and later utilizing that information during DAG Instruction Selection in order to match given pattern based on this marking. I’m wondering if marking IR instruction utilizing Metadata is good idea. But how later pass that information to DAG and appropriately mark in

*TL;DR:* Defining memory functions in C / C++ results in a chicken and egg problem. Clang can mutate the code into semantically equivalent calls to libc. None of `-fno-builtin-memcpy`, `-ffreestanding` nor `-nostdlib` provide a satisfactory answer to the problem. *Goal* Create libc's memory functions (aka `memcpy`, `memset`, `memcmp`, ...) in C++ to benefit from compiler's knowledge and

Ah. I understand now. I was considering roughly the same, but wasn't sure whether that or rich rules was preferable. -- Kimee On Sat, 2019-04-27 at 01:39 +0200, Thibaut Perrin wrote: > No, I think the rules you created might have a better place in a > custom xml file instead of being given to firewall cmd directly :) > > On Fri, 26 Apr 2019 at 23:01, Kimberlee Integer Model

Hi, When using Wine to run Windows ARM64 executables on Linux, there's one major ABI incompatibility between the two; Windows treats the x18 register as the reserved platform register, while it is free to be clobbered anywhere in code on Linux. The Wine code sets up this register before passing control over to the Windows executable code, but whenever the Windows code calls a function

Hi Peter, Thanks for the response. If we set aside the discussion of the relationship between sections and the application of the "location" or "at" attribute for a moment, do you have any objections to the proposed method of encoding metadata information about symbols (whether they are associated with actual data objects, functions, or sections) in the ELF object file?

...ame time that the current opt-viewer mechanism was being developed and we didn't manage to get aligned with that. I'm hoping that we can correct that now. -------------- next part -------------- An HTML attachment was scrubbed...

Hi Thomas. Some minor things and some bikeshedding too. One general^Wbikeshedding thing - unint32_t is used in many places. And then s64 in one place. Seems like two concepts are mixed. Maybe be consistent and use u32, s32 everywhere? I did not read the code carefully enough to understand it. I cannot give a r-b or a-b - as I feel I need to understand it to do so.
