#  The output of -v is printed to stderr.
#
#  The following command redirects stderr to v.out
#
gcc -v main.c 2> v.out

#
#  Some greps on v.out  
#
grep 'gcc version'           v.out
grep 'Thread model'          v.out
grep 'Configured with'       v.out
grep 'Target'                v.out
grep 'COLLECT_LTO_WRAPPER'   v.out
grep 'COLLECT_GCC'           v.out

#
#   With the .S suffix, cc1 is invoked first with
#   the -E flag
#
gcc -v assembly.S 2> v.out

#
#   With the .i suffix, cc1 is invoked with the -fpreprocessed flag
#
gcc -v already-preprocessed.i 2> v.out
