AMDGPU/GlobalISel: Report RegBankLegalize errors using reportGISelFailure
Use standard GlobalISel error reporting with reportGISelFailure
and pass returning false instead of llvm_unreachable.
Also enables -global-isel-abort=0 or 2 for -global-isel -new-reg-bank-select.
Note: new-reg-bank-select with abort 0 or 2 runs LCSSA,
while "intended use" without abort or with abort 1 does not run LCSSA.
[clang][Docs] Move debug info flags into groups (#169942)
This moves a few existing debug info flags that were floating in the
general pool of unorganised flags over to the existing groups for debug
info flags (so that they are presented together in documentation).
As a tiny further tweak, this also fixes the spelling of "DWARF" in the
flag docs for consistency with other flags.
[LV] Add predicated store sinking tests requiring further noalias checks
Add additional tests where extra no-alias checks are needed, as future
extensions of https://github.com/llvm/llvm-project/pull/168771.
GlobalISel: Use LibcallLoweringInfo analysis in legalizer
This is mostly boilerplate to move various freestanding utility
functions into LegalizerHelper. LibcallLoweringInfo is currently
optional, mostly because threading it through assorted other
uses of LegalizerHelper is more difficult.
I had a lot of trouble getting this to work in the legacy pass
manager with setRequiresCodeGenSCCOrder, and am not happy with the
result. A sub-pass manager is introduced and this is invalidated,
so we're re-computing this unnecessarily.
[ARM] Introduce intrinsics for MVE minnm/maxnm under strict-fp. (#169795)
Similar to #169156 again, this is mostly for denormal handling as there
is no rounding step in a minnum/maxnum.
