"git remote get-url" is apparently fairly new, the old version is "git config remote.origin.url". Might be worth using that for compatibility.

Hi all, During the review of https://reviews.llvm.org/D65997 an issue was revealed, which relates to the decision of how compiler should represents constrained floating point operations. If a floating point operation requires rounding mode or exception behavior different from the default, it should be represented by constrained intrinsic (

See https://reviews.llvm.org/D63036 for the full patch and description. Essentially, the Constant::canTrap API is going away. To make this work, the semantics of division and remainder constant expressions are changing slightly, so division by zero produces poison, not undefined behavior. (The corresponding instructions still have undefined behavior.) This change should make writing and

Hi Craig: I tried that, now the function is like this: ; Function Attrs: norecurse nounwind readnone ssp uwtable define { double, double } @add(double, double, double, double) local_unnamed_addr #0 {   %5 = call double @llvm.experimental.constrained.fadd(double %0, double %2, metadata !"round.downward", metadata !"fpexcept.ignore")   %6 = fadd double %1, %3

Hi everyone, The WebAssembly backend recently had Bug 39448 <https://bugs.llvm.org/show_bug.cgi?id=39448> filed against it because NaN payloads in floating-point immediates are not preserved through compilation on 32-bit builds. I took a look and the corruption takes place when the immediates are converted from APFloats to be stored as native doubles in MCOperand. I assume this bug only

Hey, First time using LLVM's git repo. Does 'git llvm push' take a really long time to work? I've tried to push a couple of times now and receive a message like: <scrubbed> llvm-project/llvm> git llvm push Pushing 1 commit: 2159c44 Update PatternMatcher for FNeg Committed 2159c44 to svn. <scrubbed> llvm-project/llvm> The svn repo never seems to update

I've run update_llc_test_checks on a set of tests and am seeing some weird behavior. The CHECK lines appear directly after the function's first line, even if there are multiple arguments. E.g.: define <vscale x 4 x i32> @sel_nxv4i32(<vscale x 4 x i1> %p, ; CHECK-LABEL: sel_nxv4i32: ; CHECK: // %bb.0: ; CHECK-NEXT: mov z0.s, p0/m, z1.s ; CHECK-NEXT: ret

Hi, During the discussion on introducing scalable vectors we established that we could use the canonical IR form for splats of scalable vector types (insert element into lane 0 of an undef vector, shuffle that with another undef vector of the same type and a zeroinitializer mask). We do run into a problem for lowering to SelectionDAG however, since the canonical form there is a BUILD_VECTOR with

About ftrapping-math: I think we should eliminate ftrapping-math, a boolean option, because it overlaps with ffp-exception-behavior, a 3 valued option. Or we can keep it in the clang driver for compatibility, but it should be rewritten by clang driver into ffp-exception-behavior=ignore and ffp-exception-behavior=strict. There are various fields in llvm and/or clang that maintain Boolean
