* backends: Add frame pointer unwinding for LoongArchYouling Tang2023-05-091-0/+1
| | | | | | | | | | | If we don't find any debug information for a given frame, we usually cannot unwind any further. However, the binary in question might have been compiled with frame pointers, in which case we can look up the well known frame pointer locations in the stack snapshot and use them to bridge the frames without debug information.

Before applying the patch: $ ./src/elflint --gnu-ld ./src/elflint section [35] '.symtab': _GLOBAL_OFFSET_TABLE_ symbol value 0x68548 does not match .got.plt section address 0x68238 After applying the patch: $ ./src/elflint --gnu-ld ./src/elflint No errors Signed-off-by: Liwei Ge <[email protected]> Signed-off-by: Youling Tang <[email protected]>
* LoongArch: implemented a basic machine flag checkAlexey Sheplyakov2023-03-201-0/+1
| | | | | | | | | | | | | | | | | | | | With this patch I can use eu-elflint to verify LoongArch ELF binaries. Previously eu-elflint was complaining about invalid machine flags: $ ./src/elflint --gnu-ld ./src/elflint invalid machine flags: 0x43 $ echo $? 1 * backends/loongarch_symbol.c (loongarch_init): Hook machine_flag_check. * backends/loongarch_symbol.c (loongarch_machine_flag_check): New function. https://sourceware.org/bugzilla/show_bug.cgi?id=30251 Signed-off-by: Alexey Sheplyakov <[email protected]>
