Subject: [PATCH] xtensa: fix signedness of gas relocations
|
|
|
|
Change 1058c7532d0b "Use signed data type for R_XTENSA_DIFF* relocation
|
|
offsets." changed signedness of BFD_RELOC_XTENSA_DIFF* relocations
|
|
substituted for BFD_RELOC_*. This made it impossible to encode arbitrary
|
|
8-, 16- and 32-bit values, which broke e.g. debug info encoding by .loc
|
|
directive. Revert this part and add test.

|
|
substitutions for BFD_RELOC_* as unsigned.
