I've given a quick look at the logs, and gcov-22.C says:
spawn -ignore SIGHUP
/home/tcwg-buildslave/workspace/tcwg_gnu_0/abe/builds/destdir/x86_64-pc-linux-gnu/bin/gcov
--prime-paths gcov-22.C
FAIL: g++.dg/gcov/gcov-22.C -std=gnu++98 gcov failed: spawn failed
I believe that rather than "dg-compile", it should use "dg-do run {
target native }" like almost all other gcov tests?
For the other errors:
FAIL: gcc.misc-tests/gcov-31.c (test for excess errors)
FAIL: gcc.misc-tests/gcov-32.c (test for excess errors)
the log actually says:
/gcov-31.c:12:8: error: unknown type name 'sigjmp_buf'; did you mean 'jmp_buf'?
/gcov-31.c: In function 'run_pending_traps':
/gcov-31.c:22:5: error: implicit declaration of function '__sigsetjmp'
[-Wimplicit-function-declaration]
/gcov-32.c:6:8: error: unknown type name 'sigjmp_buf'; did you mean 'jmp_buf'?
/gcov-32.c:21:19: error: passing argument 1 of 'setjmp' makes pointer
from integer without a cast [-Wint-conversion]
I haven't looked further, but does this indicate a dependency on
glibc? (this target "arm-none-eabi" uses newlib)
Thanks,
Christophe
