[InstCombine] Swap out range metadata to range attribute for cttz/ctlz/ctpop (#88776)
Since all optimizations that use range metadata now also handle range attribute, this patch replaces writes of
range metadata for call instructions to range attributes.

0c545a4412 Revert "clang: Use new frexp intrinsic for builtins and add f16 version"
This caused asserts in some Android and Windows builds:

SelectionDAGNodes.h:1138: llvm::SDValue::SDValue(SDNode *, unsigned int):
Assertion `(!Node || !ResNo || ResNo < Node->getNumValues()) && "Invalid result number for the given node!"' failed.

See comment on 85bdea023f

Also revert "HIP: Use frexp builtins in math headers"
which seems to depend on this change.

This reverts commit 85bdea023f5116f789095b606554739403042a21.
This reverts commit bf8e92c0e792cbe3c9cc50607a1e33c6912ffd0e.

aae20a7421 [CodeGenOpenCL] Convert some tests to opaque pointers (NFC) 2023-01-05 10:57:30 +01:00

7068aa9841 Strengthen -Wint-conversion to default to an error
Clang has traditionally allowed C programs to implicitly convert
integers to pointers and pointers to integers, despite it not being
valid to do so except under special circumstances (like converting the
integer 0, which is the null pointer constant, to a pointer). In C89,
this would result in undefined behavior per 3.3.4, and in C99 this rule
was strengthened to be a constraint violation instead. Constraint
violations are most often handled as an error.

This patch changes the warning to default to an error in all C modes
(it is already an error in C++). This gives us better security posture
by calling out potential programmer mistakes in code but still allows
users who need this behavior to use -Wno-error=int-conversion to retain
the warning behavior, or -Wno-int-conversion to silence the diagnostic
entirely.

532dc62b90 [OpaquePtrs][Clang] Add -no-opaque-pointers to tests (NFC)
This adds -no-opaque-pointers to clang tests whose output will
change when opaque pointers are enabled by default. This is
intended to be part of the migration approach described in
https://discourse.llvm.org/t/enabling-opaque-pointers-by-default/61322/9.

The patch has been produced by replacing %clang_cc1 with
%clang_cc1 -no-opaque-pointers for tests that fail with opaque
pointers enabled. Worth noting that this doesn't cover all tests,
there's a remaining ~40 tests not using %clang_cc1 that will need
a followup change.
