Fix testcases compilation failures due to unused variables.
|
|
* ld-elfcomm/common1b.c (dummy1): Mark the variable for GCC as USED.
|
|
* ld-shared/main.c (main): Move the P variable only to the places where
|
|
it is used.

Provide virtual target "cfi" for targets supporting CFI.
|
|
* ld-elf/eh-frame-hdr.d: Replace target and xfail statements by single
|
|
`target: cfi'.
|
|
* ld-elf/eh-group.exp: Call check_as_cfi instead of is_elf_format.
|
|
* ld-elf/eh-group1.s, elf/eh-group2.s: Use more compatible section
|
|
flags prefix '%'.
|
|
* ld-elf/eh5.d: Replace target statement by `target: cfi' with an Alpha
|
|
exception. Relax the `Code alignment factor' matching.
|
|
* lib/ld-lib.exp: Rename istarget as istarget_ld.
|
|
(istarget, check_as_cfi): New procedure.
|
|
(run_dump_test): New comment for the virtual target `cfi'.
