Subject: MIPS: fix some ld testcases with compiler
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=a0631c1501c113c04891c9a24a9ff5276257f28d;p=binutils-gdb.git

MIPS: fix some ld testcases with compiler

1. config/default.exp:
	use -mabi=32 not for -gnuabi64
	xfail_from_runlist: remove an element and mark it xfail.
2. ld-elf/indirect.exp: xfail
	indirect5a indirect5b indirect6a indirect6b
	indirect5c indirect5d indirect6c indirect6d
3. ld-elf/pr23658-2: mips output is not common
4. ld-elf/shared.exp: non-run on mips: Build libpr16496b.so
5. ld-elfvers/vers.exp:
	xfail vers4, vers4b
	no-run on mips: vers24a, vers24b, vers24c
6. ld-gc/gc.exp: add -KPIC into asflags for pr13683, pr14265, pr19161
7. ld-mips-elf/mips-elf.exp:
	use noarch for mips16-local-stubs-1, since it use -mips4
8. ld-plugin/lto.exp:
	no-run on mips/linux: PR ld/12982
	add -KPIC into asflags for lto-3r, lto-5r, PR ld/19317 (2)
	xfail PR ld/15323 (4), PR ld/19317 (3)
9. ld-plugin/plugin.exp: xfail
	plugin claimfile lost symbol
	plugin claimfile replace symbol
	plugin claimfile replace symbol
	plugin claimfile lost symbol with source
	plugin claimfile replace symbol with source
	plugin claimfile resolve symbol with source
	plugin 2 with source lib
	load plugin 2 with source
	plugin 3 with source lib
	load plugin 3 with source
11. ld-selective/selective.exp: add -fno-PIC, which is needed for -mno-abicalls
12. ld-shared/shared.exp: xfail shared (non PIC), shared (PIC main, non PIC so)
