Nikita Popov	39db5e1ed8	[CodeGen] Convert tests to opaque pointers (NFC) ... Conversion performed using the script at: https://gist.github.com/nikic/98357b71fd67756b0f064c9517b62a34 These are only tests where no manual fixup was required.	2022-10-07 14:22:00 +02:00
Nikita Popov	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.

hyeongyu kim	1b1c8d83d3	[Clang/Test]: Rename enable_noundef_analysis to disable-noundef-analysis and turn it off by default ... Turning on `enable_noundef_analysis` flag allows better codegen by removing freeze instructions. I modified clang by renaming `enable_noundef_analysis` flag to `disable-noundef-analysis` and turning it off by default.

Sami Tolvanen	ec2e26eaf6	[Clang] Add __builtin_function_start ... Control-Flow Integrity (CFI) replaces references to address-taken functions with pointers to the CFI jump table. This is a problem for low-level code, such as operating system kernels, which may need the address of an actual function body without the jump table indirection. This change adds the __builtin_function_start() builtin, which accepts an argument that can be constant-evaluated to a function, and returns the address of the function body.
