Marko Mäkelä c36834c832 MDEV-20377: Make WITH_MSAN more usable ... MemorySanitizer (clang -fsanitize=memory) requires that all code be compiled with instrumentation enabled. The only exception is the C runtime library. Failure to use instrumented libraries will cause bogus messages about memory being uninitialized. In WITH_MSAN builds, we must avoid calling getservbyname(), because even though it is a standard library function, it is not instrumented, not even in clang 10. Note: Before MariaDB Server 10.5, ./mtr will typically fail due to the old PCRE library, which was updated in MDEV-14024. The following cmake options were tested on 10.5 in commit 94d0bb4dbe: cmake \ -DCMAKE_C_FLAGS='-march=native -O2' \ -DCMAKE_CXX_FLAGS='-stdlib=libc++ -march=native -O2' \ -DWITH_EMBEDDED_SERVER=OFF -DWITH_UNIT_TESTS=OFF -DCMAKE_BUILD_TYPE=Debug \ -DWITH_INNODB_{BZIP2,LZ4,LZMA,LZO,SNAPPY}=OFF \ -DPLUGIN_{ARCHIVE,TOKUDB,MROONGA,OQGRAPH,ROCKSDB,CONNECT,SPIDER}=NO \ -DWITH_SAFEMALLOC=OFF \ -DWITH_{ZLIB,SSL,PCRE}=bundled \ -DHAVE_LIBAIO_H=0 \ -DWITH_MSAN=ON MEM_MAKE_DEFINED(): An alias for VALGRIND_MAKE_MEM_DEFINED() and __msan_unpoison(). MEM_GET_VBITS(), MEM_SET_VBITS(): Aliases for VALGRIND_GET_VBITS(), VALGRIND_SET_VBITS(), __msan_copy_shadow(). InnoDB: Replace the UNIV_MEM_ macros with corresponding MEM_ macros. ut_crc32_8_hw(), ut_crc32_64_low_hw(): Use the compiler built-in functions instead of inline assembler when building WITH_MSAN. This will require at least -msse4.2 when building for IA-32 or AMD64. The inline assembler would not be instrumented, and would thus cause bogus failures.		2020-07-01 17:23:00 +03:00
