RE: [RFC] Trying to fix testsuite/gdb.arch/i386-sse.exp pattern problem
I simplified the test as much as I could:
$ cat ../../../src/gdb/testsuite/gdb.arch/test.exp
gdb_exit
gdb_start
gdb_test "print 1122233" \
".* = 1*2*.*" \
"Check int constant"
gdb_test "print 1122233" \
".* = 1{1,}2{1,}.*" \
"Check int constant with curly braces"
$ make check RUNTESTFLAGS="--debug gdb.arch/test.exp"
Nothing to be done for all...
rootme=`pwd`; export rootme; \
srcdir=../../../src/gdb/testsuite ; export srcdir ; \
EXPECT=`if [ -f ${rootme}/../../expect/expect ] ; then echo
${rootme}/..
/../expect/expect ; else echo expect ; fi` ; export EXPECT ; \
EXEEXT=.exe ; export EXEEXT ; \
LD_LIBRARY_PATH=$rootme/../../expect:$rootme/../../libstdc++:$rootme/../
../tk/unix:$rootme/../../tcl/unix:$rootme/../../bfd:$rootme/../../opcodes:$L
D_LI
BRARY_PATH; \
export LD_LIBRARY_PATH; \
if [ -f ${rootme}/../../expect/expect ] ; then \
TCL_LIBRARY=${srcdir}/../../tcl/library ; \
export TCL_LIBRARY ; fi ; \
` if [ -f ${srcdir}/../../dejagnu/runtest ]; then echo
${srcdir}/../../d
ejagnu/runtest; else if [ "i686-pc-cygwin" = "i686-pc-cygwin" ]; then echo
runte
st; else t='s,y,y,'; echo runtest | sed -e $t; fi; fi` --debug

make: *** [just-check] Error 1
The dbg.log shows that:
expect: does "print 1122233\r\n$1 = 1122233\r\n(gdb) " (spawn_id 7) match
regula
r expression ".*A problem internal to GDB has been detected"? no^M
"\*\*\* DOSEXIT code.*"? no^M
"[\r\n]*(.* = 1*2*.*)[\r\n]+\(gdb\) $"? yes^M
But later:
expect: does "print 1122233\r\n$2 = 1122233\r\n(gdb) " (spawn_id 7) match
regula
r expression ".*A problem internal to GDB has been detected"? no^M
"\*\*\* DOSEXIT code.*"? no^M
"[\r\n]*(.* = 1{1,}2{1,}.*)[\r\n]+\(gdb\) $"? no^M
So even that simple test fails :(
