--- Comment #5 from David Kredba <nheghathivhistha at gmail dot com> ---
I tried to write a script for c-reduce. It writes output from compiler in two
steps but grep not waits and c-reduce not wanted to accept it as valid for
reducing case becuse test error level was not OK.
When I modified it this way:
#!/bin/bash
TESTCASE=${1:-testcase.i}
x86_64-pc-linux-gnu-gcc -std=gnu99 -Wall -Wpointer-arith
-Wmissing-declarations -Wformat=2 -Wstrict-prototypes -Wmissing-prototypes
-Wnested-externs -Wbad-function-cast -Wold-style-definition
-Wdeclaration-after-statement -Wunused -Wuninitialized -Wshadow
-Wmissing-noreturn -Wmissing-format-attribute -Wredundant-decls -Wlogical-op
-Werror=implicit -Werror=nonnull -Werror=init-self -Werror=main
-Werror=missing-braces -Werror=sequence-point -Werror=return-type
-Werror=trigraphs -Werror=array-bounds -Werror=write-strings -Werror=address
-Werror=int-to-pointer-cast -Werror=pointer-to-int-cast -fno-strict-aliasing
-fvisibility=hidden -O2 -ggdb -pipe -march=native -mtune=native -flto=4 -o
/dev/null /home/dave2/$TESTCASE /home/dave2/libxservertest.a >
/home/dave2/test.txt 2>&1
cat /home/dave2/test.txt | grep -q 'error: array subscript is below array
bounds'
if ! test $? = 0; then
exit 1
fi
exit 0
then grep was returning expected return code but c-reduce was not able to
remove any line. I think I am missing some very basic thing here :-(.
PS I know that grep can be called with a file name without using cat and pipe
but it not wanted to work too.
