--- Comment #7 from Rainer Orth <ro at CeBiTec dot Uni-Bielefeld.DE> --- > --- Comment #5 from Joel Brobecker <brobecker at gnat dot com> --- > (Thanks Nick for the patch) Indeed, thanks a lot. However, I think we can do better than disabling the ld sparc*tests on Solaris. Even if we omit support for the elf32_sparc and and elf64_sparc emulations, it should be possible to handle that with a snippet like the following in sparc.exp (tested a very long time ago, not sure if it still works as is): # Solaris/SPARC ld uses elf??-sparc_sol2 emulations. if { [istarget "*-*-solaris*"] } { set options_regsub(ld) {-m(\\S+) -m\\1_sol2} verbose "solaris: options_regsub(ld)" } Alan has also done some of the work by making the dump files accept both elf32-sparc and elf32-sparc-sol2. The ugliest part (or one which really requires a general solution) is that the Solaris ABI couple of additional symbols into the output files, like /var/gcc/binutils/sparcv9/obj/binutils/ld/../binutils/readelf -WSsrl tmpdir/libtlssunpic32.so regexp_diff match failure regexp "^.* TLS +GLOBAL +DEFAULT +7 sg8$" line " 4: 00012188 0 OBJECT LOCAL DEFAULT 11 _END_" regexp_diff match failure regexp "^.* TLS +GLOBAL +DEFAULT +7 sg3$" line " 5: 00001000 0 OBJECT LOCAL DEFAULT 6 _START_" [...] One possible solution to that is to have separate copies for Solaris (as done in gas in a few cases for x86), but that quickly becomes unmaintainable with master dump and Solaris copy beginning to drift apart. What I think would be a general solution is having support for conditionals in the dump files, something like #cond <cond>: GLOB|PROC set condition cond to true if GLOB matches or PROC returns true, false otherwise, e.g. #cond SOLARIS: *-*-solaris2* run_dump_test calls to regexp_diff for comparisons #if:<cond> <rest of line> e.g. #if:SOLARIS <rest of line> need more: #if:SOLARIS #else for individual lines, maybe also for blocks? then we need #if:SOLARIS <lines> #else <lines> #endif no nesting for simplicity's sake Just a general idea because this issue seems to come up on other targets, too. I haven't even started thinking about implemented this and probably won't for quite some time. Rainer -- You are receiving this mail because: You are on the CC list for the bug.
