There is no generic mechanism as far as I know. You can look at AsmPrinter.cpp/emitComments() to see what situations trigger comments at the moment. - Matthias > On Feb 3, 2018, at 4:40 AM, Martin J.

When I am constructing sequences of instructions during custom lowering, I would like to be able to also add a comment that appears in the generated assembly with '-S -fverbose-asm'. There is a large set of 'add*' functions to attach additional information to the MI, but I don't see one for adding comments. Is there a method I can call to attach an arbitrary string

Hi, Is there a way to print the register liveness information into the assembly file or as some intermediate listing? To be more precise, I am looking at figuring out the following information in an assembly file/listing. Say, for simplicity, our register set is only { rsp, rbp, eax } subq $16, %rsp // rsp is killed here, eax and rbp are live movl $0, -4(%rbp) // rbp is killed here,

Our TCE backend (which is not in the official llvm repo) benefits greatly from information that which memory load/store is a spill generated by register allocation. These spill memory operation can never alias with other memory operations, and our own instruction scheduler can optimize much better with better alias information. I have created a code which adds marking these spill

...I, unsigned int Op, .. + return true; + } else { + // Check for post-frame index elimination Please eliminate the 'else' to avoid nesting. Also, please terminate your comment with a period. There are several comments in the patch that need to be terminated. In AsmPrinter::EmitComments please make "Newline" be a bool "NeedsNewline" instead of a char with only two states (uninitialized and '\n'). Please initialize it. Overall, the approach looks very nice. Please commit this (with the changes above) as a series of patches: 1. Constify the Ta...

...mpile time improvement compare to without IPRA is about 4 to 8 minutes. Study: ===== This week I study code responsible for adding spill and restore for callee saved registers. Also studied how calling convention is defined in target specific .td files. I studied AsmPrinter.cpp and specifically emitComments() method which is responsible for adding comments in llvm generated assembly files. I also studied about some linkage type in LLMV IR like ‘internal’ which represent local function in module. Plan for next week: 1) Submit patch related to local function optimization for review 2) Find more pos...

Attached is a patch to print asm comments for spill information. We've discussed the mechanisms before but I wanted to run the patch by everyone before I start to commit pieces. -Dave -------------- next part -------------- A non-text attachment was scrubbed...
