           Summary: 64bit-out.go, select5-out.go, tmp.go compilation times
                    out
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: go
        AssignedTo: ian@airs.com
        ReportedBy: ro@gcc.gnu.org
              Host: sparc-sun-solaris2.*
            Target: sparc-sun-solaris2.*
             Build: sparc-sun-solaris2.*


3 go testcases time out while compiling on Solaris 2/SPARC:

FAIL: ./64bit-out.go compilation,  -O2 -g 
FAIL: ./select5-out.go compilation,  -O2 -g 
FAIL: ./tmp.go compilation,  -O2 -g 

E.g., compiling 64bit-out.go (an 1.3 MB source file) on an unloaded 1.35 GHz
UltraSPARC IV+ takes

real        4:13.59
user        4:12.51
sys            0.84

which is dangerously close to the default 300 s timeout.

It's way worse on a 250 MHz MIPS R10k:

real    17:17.42
user    17:12.24
sys         1.21

I thing such a test (haven't looked in more detail into the others) is way
over the top.

Should be fixed now.  Let me know if you still see problems.

Not with these three.  Only

Running target unix/-m64
FAIL: go.test/test/chan/doubleselect.go execution,  -O2 -g 
WARNING: program timed out.

times out consistently (64-bit only, Solaris 9 to 11).
