Yonghong Song 52e5ec1f09 BPF: fix relocation types in lib/Object/RelocationResolver.cpp ... Commit 6a2ea84600ba ("BPF: Add more relocation kinds") added new relocations R_BPF_64_ABS64 and R_BPF_64_ABS32 for normal 64-bit and 32-bit data relocations. This is to replace some of functionalities with R_BPF_64_64 and R_BPF_64_32 so that new R_BPF_64_64 and R_BPF_64_32 semantics are for ld_imm64 and call instructions only. The BPF support in lib/Object/RelocationResolver.cpp is used to perform normal data relocations for the case like DWARFObjInMemory with an object file (search function getRelocationResolver() in file DebugInfo/DWARF/DWARFContext.cpp) or llvm-readobj to dump ".stack_sizes" section data. In all these casees, normal 64-bit and 32-bit relocations are performed and such resolution resolution is exactly what implemented in RelocationResolver.cpp. But Commit 6a2ea84600ba missed to change R_BPF_64_64/R_BPF_64_32 to R_BPF_64_ABS64/R_BPF_64_ABS32. This patch fixed the issue and added a test for it with llvm-readobj dumping ".stack_sizes" section. Differential Revision: https://reviews.llvm.org/D103864		2021-06-07 20:59:21 -07:00
