Example CMHG file (from GDBServer)
E.g.:
--8<--
error_identifiers: \
kErr_Error1("Error1") \
kErr_Error2("Error2") \
kErr_Error3("Error3")
--8<--
gcc 4.6.0 (20100915 (experimental) [trunk revision 164317]) preprocessor
transforms this into:
--8<--
# 1 "test-preprocess.c"
# 1 "<built-in>"
# 1 "<command-line>"
# 1 "test-preprocess.c"
error_identifiers:
kErr_Error1("Error1")
kErr_Error2("Error2")
kErr_Error3("Error3")
--8<--
I.e. the continuation characters got lost. cmunge will complain with:
--8<--
Serious Error: Field names should be of the form <field>: [<value>]
at ..., line ...
--8<--
While gcc 4.1.2 preprocessor transforms this into:
--8<--
# 1 "test-preprocess.c"
# 1 "<built-in>"
# 1 "<command-line>"
# 1 "test-preprocess.c"
error_identifiers: kErr_Error1("Error1") kErr_Error2("Error2")
kErr_Error3("Error3")
--8<--
and this is works fine with cmunge. Note however, that if you do not use the
preprocessor with cmunge (i.e. no -p option), above still fails so it is *not*
a preprocessor issue but something which got worse (i.e. more exposed) with the
gcc 4.6 as preprocessor.
It looks like cmunge first needs to resolve the continuation character, then
invoke the preprocessor and finally parse the result as CMHG syntax.
