From: Maciej W. Rozycki Date: Mon, 29 Jan 2018 20:10:19 +0000 (-0800) Subject: MIPS/LD/testsuite: Correct comm-data.exp test ABI/emul/endian arrangement X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=86b24e15c45bfe5085ed88280e1a5479120edce6;p=binutils-gdb.git MIPS/LD/testsuite: Correct comm-data.exp test ABI/emul/endian arrangement Update the ld-mips-elf/comm-data.exp test script to correctly select emulations for targets using non-traditional MIPS emulation and also correctly select ABIs for targets that do not support all of them, and finally use the default endianness selection to benefit targets which support only one, complementing commit 05a5feafdd38 ("Rewrite check_shared_lib_support") and removing numerous test failures such as: FAIL: MIPS o32/copyreloc common symbol override test (auxiliary shared object build) FAIL: MIPS o32/copyreloc common symbol override test FAIL: MIPS o32/nocopyreloc common symbol override test (auxiliary shared objectbuild) FAIL: MIPS o32/nocopyreloc common symbol override test FAIL: MIPS n32/copyreloc common symbol override test (auxiliary shared object build) FAIL: MIPS n32/copyreloc common symbol override test FAIL: MIPS n32/nocopyreloc common symbol override test (auxiliary shared objectbuild) FAIL: MIPS n32/nocopyreloc common symbol override test due to: .../ld/ld-new: unrecognised emulation mode: elf32btsmip Supported emulations: elf64btsmip elf64ltsmip or: .../ld/ld-new: unrecognised emulation mode: elf32btsmip Supported emulations: elf32ebmip or: .../ld/ld-new: unrecognised emulation mode: elf32btsmip Supported emulations: elf32l4300 etc., and: ERROR: -n32 -march=mips3 -EB -call_shared .../ld/testsuite/ld-mips-elf/../ld-elf/comm-data1.s: assembly failed UNRESOLVED: MIPS n32/copyreloc common symbol override test (auxiliary shared object build) ERROR: -n32 -march=mips3 -EB -call_nonpic .../ld/testsuite/ld-mips-elf/../ld-elf/comm-data2.s: assembly failed UNRESOLVED: MIPS n32/copyreloc common symbol override test ERROR: -n32 -march=mips3 -EB -call_shared .../ld/testsuite/ld-mips-elf/../ld-elf/comm-data1.s: assembly failed UNRESOLVED: MIPS n32/nocopyreloc common symbol override test (auxiliary shared object build) ERROR: -n32 -march=mips3 -EB -call_nonpic .../ld/testsuite/ld-mips-elf/../ld-elf/comm-data2.s: assembly failed UNRESOLVED: MIPS n32/nocopyreloc common symbol override test due to: Assembler messages: Fatal error: selected target format 'elf32-nbigmips' unknown and: ERROR: -64 -march=mips3 -EB -call_shared .../ld/testsuite/ld-mips-elf/../ld-elf/comm-data1.s: assembly failed UNRESOLVED: MIPS n64/copyreloc common symbol override test (auxiliary shared object build) ERROR: -64 -march=mips3 -EB --defsym ELF64=1 -call_nonpic .../ld/testsuite/ld-mips-elf/../ld-elf/comm-data2.s:assembly failed UNRESOLVED: MIPS n64/copyreloc common symbol override test ERROR: -64 -march=mips3 -EB -call_shared .../ld/testsuite/ld-mips-elf/../ld-elf/comm-data1.s: assembly failed UNRESOLVED: MIPS n64/nocopyreloc common symbol override test (auxiliary shared object build) ERROR: -64 -march=mips3 -EB --defsym ELF64=1 -call_nonpic .../ld/testsuite/ld-mips-elf/../ld-elf/comm-data2.s:assembly failed UNRESOLVED: MIPS n64/nocopyreloc common symbol override test due to: Assembler messages: Fatal error: no compiled in support for 64 bit object file format ld/ * testsuite/ld-mips-elf/comm-data.exp: Correct support for targets using non-traditional MIPS emulation or having a limited selection of ABIs available.
