ld: Fix several 32-bit SPARC plugin tests
Several ld plugin tests currently FAIL on 32-bit Solaris/SPARC: FAIL: load plugin with source FAIL: plugin claimfile lost symbol with source FAIL: plugin claimfile replace symbol with source FAIL: plugin claimfile resolve symbol with source FAIL: plugin claimfile replace file with source FAIL: plugin set symbol visibility with source FAIL: plugin ignore lib with source FAIL: plugin claimfile replace lib with source FAIL: plugin 2 with source lib FAIL: load plugin 2 with source FAIL: load plugin 2 with source and -r FAIL: plugin 3 with source lib FAIL: load plugin 3 with source FAIL: load plugin 3 with source and -r FAIL: PR ld/20070 all of them in the same way: ./ld-new: BFD (GNU Binutils) 2.34.50.20200328 internal error, aborting at /vol/src/gnu/binutils/hg/master/git/bfd/elf32-sparc.c:154 in sparc_final_write_processing This happens when bfd_get_mach returns 0 when abfd refers to a source file: $11 = { filename = 0x28c358 "/vol/src/gnu/binutils/hg/master/local/ld/testsuite/ld-plugin/func.c (symbol from plugin)", xvec = 0x24ed6c <sparc_elf32_sol2_vec>, [...] While I could find no specification what abfd's are allowed/expected in *_final_write_processing, I could find no other target that behaved the same. And indeed ignoring the 0 case fixes the failures. The code now errors for other values. 64-bit SPARC is not affected because it doesn't have a specific implementation of elf_backend_final_write_processing. Tested on sparc-sun-solaris2.11. 2020-04-07 Rainer Orth <ro@CeBiTec.Uni-Bielefeld.DE> Nick Clifton <nickc@redhat.com> * elf32-sparc.c (sparc_final_write_processing): Fix whitespace. <0>: Ignore. <default>: Error rather than abort.
