[AArch64][llvm] Separate TLBI-only feature gating from TLBIP aliases
Refactor the TLBI system operand definitions so that TLBI and TLBIP
records are emitted through separate helper multiclasses, whilst keeping
the table layout readable.
The feature-scoped wrappers now apply FeatureTLB_RMI, FeatureRME, and
FeatureTLBIW only to TLBI records (it was previously incorrectly also
applied to TLBIP instructions), while TLBIP aliases remain gated only
by FeatureD128, including their nXS forms.
Update testcases accordingly.
[Polly] Avoid __builtin_assume circular context reasoning (#189350)
The conversion of SCEVs to isl::pw_aff may only be valid under
conditions that have to be confirmed via RTC. This also happens with
__builtin_assume. These user-added assumptions are then added to
ScopInfo::Context. However, the conclusion in ScopInfo::Context is then
also used to simplify ("gist") its own RTC preconditions in
ScopInfo::AssumedContext and ScopInfo::InvalidContext away.
Avoid by adding user assumptions with preconditions to
ScopInfo::DefinedBehaviourContext instead, which is not used to simplify
AssumedContext/InvalidContext.
Fixes #187922
Thanks @thapgua for the report
[BasicBlockUtils] Fixed LoopInfo update in UpdateAnalysisInformation() (#177147)
SplitLandingPadPredecessors() results in an irreducible loop
and makes LoopInfo invalid. Verification results in a crash:
Assertion `CB != OutsideLoopPreds[i] && "Loop has multiple entry
points!"' failed.
Created a new test with a broken LoopInfo after
SplitLandingPadPredecessors().
The test @split-lp-predecessors-test() after
SplitBlockPredecessors(catch_dest, { loop }, "", DT, LI) changes to
the following IR where the loop {%catch_dest} gets into irreducible
loop {%catch_dest.split-lp, %catch_dest}:
```
define void @split-lp-predecessors-test() personality ptr null {
entry:
invoke void @foo()
to label %loop unwind label %catch_dest.split-lp

tex-overpic: update to 2.2
The new version offers the macros \width, \height and \depth
as well as the dimension register \totalheight within the
environments “overpic” and “Overpic”.
[InstCombine] Fold X * ldexp(1.0, Y) -> ldexp(X, Y). (#188493)
This would avoid the FMUL in sequences such as
[these](https://godbolt.org/z/xhqfe5sb1).
revert the stupid decision to not pre-selecting accept buttons in file dialogs
now my precious enter key is working again in the file dialogs
Yes, you read it right:
// GTK's internal response IDs use negative integers (eg. GTK_RESPONSE_CANCEL),
// leaving zero and positive integers for application-defined response IDs. Use
// zero for the accept response type since GTK will preselect
// GTK_RESPONSE_ACCEPT as the default button, which should be avoided to prevent
// an exploit where the user is instructed to hold Enter before the dialog
// appears.
[clang][x86] Fix the return type of the cvtpd2dq builtin (#189254)
The CVTPD2DQ instruction converts packed 64-bit floating-point values to
packed 32-bit signed integer values. This patch fixes the return type of
the corresponding builtin, which previously returned a vector of two
64-bit signed integers. The new behavior is in line with the return type
of the CVTTPD2DQ builtin.
