-Subject: [PATCH] xtensa: fix PR ld/25861
|
|
|
|
-
|
|
|
|
-Introduce new relaxations XTENSA_PDIFF{8,16,32} for positive differences
|
|
|
|
-(subtracted symbol precedes diminished symbol) and XTENSA_NDIFF{8,16,32}
|
|
|
|
-for negative differences (subtracted symbol follows diminished symbol).
|
|
|
|
-Don't generate XTENSA_DIFF relocations in the assembler, generate
|
|
|
|
-XTENSA_PDIFF or XTENSA_NDIFF based on relative symbol position.
|
|
|
|
-
|
|
|
|
-Handle XTENSA_DIFF in BFD for compatibility with old object files.
|
|
|
|
-Handle XTENSA_PDIFF and XTENSA_NDIFF in BFD, treating difference value
|
|
|
|
-as unsigned.
