After playing a bit with the newly introduced hardware loop framework I realize that the llvm.set.loop.iterations intrinsic takes as argument the number of iterations the loop will execute. In fact it goes all the way to, on IR, insert an addition of constant 1 to the number of taken backedges returned by SCEV. If the machine instruction realizing the loop is interested in the number of

Hi, Looking at the output of e.g. llc -mtriple=x86_64-unknown-linux-gnu test/CodeGen/X86/pre-coalesce.ll -debug-pass=Executions Why is it that 'Basic Alias Analysis (stateless AA impl)' is freed much earlier than 'Function Alias Analysis Results' even though the latter depends on the former (at least AFAICT by looking at lib/Analysis/AliasAnalysis.cpp)? Thanks! -Markus

Hi, I recently worked on an issue where I realized that -print-after-all does not cover all passes run by the pass manager. E.g. it seems that loop passes are not fully covered and I could find that loop transformations showed up in the dump of the next non-loop pass (which happened to be 'Combine redundant instructions' and that was rather confusing). Specifying both -print-before-all

I am confused about the rules for when upper and lower case letters should be used in MIR. As an example our downstream target has upper case letters in its sub-register indices and as a result we cannot import exported MIR without manually 'lower casing' it first which is obviously rather annoying. Looking in https://llvm.org/docs/MIRLangRef.html it is stated that instruction names are

Right, that could very well be sufficient for this particular case so

The Loop Strength Reduction pass appears to break debug information even for the most basic input. I believe this is a well known issue already (see https://bugs.llvm.org/show_bug.cgi?id=38815) but I also believe that it deserve some extra attention. Consider the following input compiled with 'clang -g -O3 foo.c -mllvm -print-after-all' --- void foo(unsigned char *p) { #pragma clang loop

I have tow vectors one is the subset of another x is a subset of X Both are vectors with n elements X[X %in% x] would give me x again rite because it is a subset but i want all those are not in x from X.

Hello, Could someone explain to me what the rules are for concatenation of DWARF location expressions? For example in lib/CodeGen/PrologEpilogInserter.cpp there is a call to DIExpression::prepend to concatenate the stack slot address of a variable to an existing expression. Now the problem here is that the former is a 'Memory location description' while the latter could very well be a

In short: Shall analysis of a SCEV expression be allowed even though part of the IR that was analyzed to build the SCEV expression has been removed? In more detail with background: About a month ago I landed https://reviews.llvm.org/D87494 where SCEV is used to do additional debug-info salvaging in LSR. The idea was to compute (and store) a SCEV of what llvm.dbg.value intrinsics inside the loop
