* [Bug testsuite/28837] New: need to prune "can't find atom for N_GSYM stabs" warnings on Darwin for -m64 @ 2006-08-24 15:40 howarth at nitro dot med dot uc dot edu 2006-10-03 20:50 ` [Bug testsuite/28837] " geoffk at gcc dot gnu dot org ` (3 more replies) 0 siblings, 4 replies; 5+ messages in thread From: howarth at nitro dot med dot uc dot edu @ 2006-08-24 15:40 UTC (permalink / raw) To: gcc-bugs Currently the ld64 on Darwin seems to create warnings of the form... can't find atom for N_GSYM stabs i:G(0,2) in /var/tmp//cc6KtMzX.o when compiling Fortran COMMON blocks at -m64 with the -g flag. These warnings incorrectly cause about 38 apparent fortran testsuite failures on Darwin. This problem can be suppressed until the issue causing the warnings (whose cause is currently unknown) is addressed. The following patch (sorry about the unified format) allows these warnings to be pruned and ignored during a -m64 make check. --- gcc-4.2-20060822/gcc/testsuite/lib/prune.exp.org 2006-08-23 18:33:56.000000000 -0400 +++ gcc-4.2-20060822/gcc/testsuite/lib/prune.exp 2006-08-23 18:41:28.000000000 -0400 @@ -43,6 +43,7 @@ regsub -all "(^|\n)\[^\n\]*file path prefix \[^\n\]* never used" $text "" text regsub -all "(^|\n)\[^\n\]*linker input file unused since linking not done" $text "" text + regsub -all "(^|\n)can't find atom for N_GSYM stabs \[^\n\]* in \[^\n\]*" $text "" text #send_user "After:$text\n" return $text With this patch in place the fortran testsuite failures for -m64 are identical to those for -m32 with three unexpected passes.

The patch may be wrong, but so far nobody cared to fix the "underlying bug" or even bothered to explain its origin and how to fix it!-( -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=28837 ^ permalink raw reply [flat|nested] 5+ messages in thread
