Bug #: 50654
Summary: Many Go tests fail on emutls targets
Classification: Unclassified
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: go
AssignedTo: ian@airs.com
ReportedBy: ro@gcc.gnu.org
Host: *-*-solaris2.[89]
Target: *-*-solaris2.[89]
Build: *-*-solaris2.[89]
Between 20110930 and 20111006, many Go tests started to FAIL on Solaris 8 and
9/x86 (haven't tried SPARC yet) with Sun as, thus they use emutls:
output is:
Undefined first referenced
symbol in file
__emutls_v.__go_panic_defer
/var/gcc/regression/trunk/8-gcc/build/i386-pc-solaris2.8/./libgo/.libs/libgo.so
__emutls_v.m
/var/gcc/regression/trunk/8-gcc/build/i386-pc-solaris2.8/./libgo/.libs/libgo.so
ld: fatal: Symbol referencing errors. No output written to
/var/gcc/regression/trunk/8-gcc/build/gcc/testsuite/go/array-1.x
collect2: error: ld returned 1 exit status
FAIL: go.go-torture/execute/array-1.go compilation, -O0
With gas and native TLS, the tests work fine.

Should be fixed on mainline. Although I only tested it on
x86_64-unknown-linux-gnu built using --disable-tls to force the use of emutls.
Let me know if you still see problems.

I got exactly the same set of failures on i386-pc-solaris2.11 with
--disable-tls as on i386-pc-solaris2.8 with as/ld (i.e. emutls).
> Let me know if you still see problems.
No, Solaris 8 and 9/x86 results are almost clean, and don't differ
between emutls and native TLS. I'll file new PRs for the remaining
problems if need be.
Thanks.
