perf build: Support llvm and clang support compiled in
Perf build suports llvm and clang support compiled in.
Test case 56 builtin clang support provides a test case
which is always skipped.
Link perf with the latest llvm and clang libraries and
enable this test case.
Use 'make LIBCLANGLLVM=1' to include this support.
V2: Add Library patch before -lclang-cpp
Output before:
# ./perf test 56
56: builtin clang support :
56.1: builtin clang compile C source to IR : Skip (not compiled in)
56.2: builtin clang compile C source to ELF object: Skip (not compiled in)
Output after:
# ./perf test 56
56: builtin clang support :
56.1: builtin clang compile C source to IR : Ok
56.2: builtin clang compile C source to ELF object : Ok
#
From Ian Rogers:
Build tested with LLVM 14 and 15 using:
BUILD_BPF_SKEL=1 LIBCLANGLLVM=1 LLVM_CONFIG=llvm-config-14
BUILD_BPF_SKEL=1 LIBCLANGLLVM=1 LLVM_CONFIG=llvm-config-15
