[utils] Add utils/update_cc_test_checks.py
...
A utility to update LLVM IR in C/C++ FileCheck test files.
Example RUN lines in .c/.cc test files:
// RUN: %clang -S -Os -DXX %s -o - | FileCheck %s
// RUN: %clangxx -S -Os %s -o - | FileCheck -check-prefix=IR %s
Usage:
% utils/update_cc_test_checks.py --llvm-bin=release/bin test/a.cc
% utils/update_cc_test_checks.py --c-index-test=release/bin/c-index-test --clang=release/bin/clang /tmp/c/a.cc
// NOTE: Assertions have been autogenerated by utils/update_cc_test_checks.py
// RUN: %clang -emit-llvm -S -Os -DXX %s -o - | FileCheck -check-prefix=AA %s
// RUN: %clangxx -emit-llvm -S -Os %s -o - | FileCheck -check-prefix=BB %s
using T =
#ifdef XX
int __attribute__((vector_size(16)))
#else
short __attribute__((vector_size(16)))
#endif
;
// AA-LABEL: _Z3fooDv4_i:
// AA: entry:
// AA-NEXT: %add = shl <4 x i32> %a, <i32 1, i32 1, i32 1, i32 1>
// AA-NEXT: ret <4 x i32> %add
//
// BB-LABEL: _Z3fooDv8_s:
// BB: entry:
// BB-NEXT: %add = shl <8 x i16> %a, <i16 1, i16 1, i16 1, i16 1, i16 1, i16 1, i16 1, i16 1>
// BB-NEXT: ret <8 x i16> %add
T foo(T a) {
return a + a;
}
