Summary: xgcc: error: unrecognized option '-pie' on
*-apple-darwin*
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: driver
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: domi...@lps.ens.fr
CC: mikest...@comcast.net, jos...@codesourcery.com,
r...@cebitec.uni-bielefeld.de, ia...@gcc.gnu.org
Host: *-apple-darwin*
Target: *-apple-darwin*
Build: *-apple-darwin*
On *-apple-darwin* revisions 174909 and 174910 introduced several failures in
gcc.dg/torture/tls/* with '-pie -fPIE' (see
http://gcc.gnu.org/ml/gcc-testresults/2011-06/msg01259.html ). The errors are
all (AFAICT) of the kind.
FAIL: gcc.dg/torture/tls/thr-init-1.c -O0 -pie -fpie (test for excess
errors)
Excess errors:
xgcc: error: unrecognized option '-pie'
My understanding of -pie is that it is a linker option supported by
*-apple-darwin9 and later. Apparently this option is not recognized by gcc
since at least version 4.4.4, this is why I mark this PR as a driver one
(please change it if you disagree).
A short term fix will be to remove darwin from
proc check_effective_target_pie { } {
if { [istarget *-*-darwin\[912\]*]
|| [istarget *-*-linux*] } {
return 1;
}
return 0
}
in gcc/testsuite/lib/target-supports.exp, but I think the darwin driver should
be fixed.
