This patch adds 48-bits VMA support for tsan on aarch64. As current mappings for aarch64, 48-bit VMA also supports PIE executable. This limits the mapping mechanism because the PIE address bits (usually 0aaaaXXXXXXXX) makes it harder to create a mask/xor value to include all memory regions. I think it is possible to create a large application VAM range by either dropping PIE support or tune current range. It also changes slight the way addresses are packed in SyncVar structure: previously it assumes x86_64 as the maximum VMA range. Since ID is 14 bits wide, shifting 48 bits should be ok. Tested on x86_64, ppc64le and aarch64 (39 and 48 bits VMA). llvm-svn: 277137 |
