I would like to modify how the init.c file is generated (its content). But as it is, a shell script with multiple sed invocations in a Makefile target, it's not very maintainable. Replace that with a shell script that does the same, but in a more readable way. The Makefile rule uses the "-" prefix in front of the for loop, I presume to ignore any error coming from the fact that xml-builtin.c and cp-name-parser.c are not found in the srcdir (they are generated source files). I prefer not to blindly ignore errors, so filter these files out of INIT_FILES instead (we already filter out other files). There are no expected meaningful changes to the generated init.c file. Just the _initialize_all_file declaration that is moved down and "void" in parenthesis that is removed. The new regular expression is a bit tighter than the existing one, it requires the init function to be followed by exactly ` ()`. Update bpf-tdep.c accordingly. gdb/ChangeLog: * Makefile.in (INIT_FILES_FILTER_OUT): New. (INIT_FILES): Use INIT_FILES_FILTER_OUT. (stamp-init): Use make-init-c. * bpf-tdep.c (_initialize_bpf_tdep): Remove "void". * silent-rules.mk (ECHO_INIT_C): Change. * make-init-c: New file.

# Generate the init.c source file.
|
|
#
|
|
# Usage:
|
|
#
|
|
# ./make-init-c source-files > init.c-tmp
|
|
#
|
|
# Where SOURCE-FILES is the list of source files to extract init functions from.
|
|
#
|
|
# Formatting conventions: The name of the initialization routines must begin
|
|
# with `_initialize_`, must start in column zero, and be followed with exactly
|
|
# ` ()`. For example:
|
|
#
|
|
# void
|
|
# _initialize_foo ()
|
|
# {
|
|
# ...
|
|
# }
|
|
#
|
|
|
|
# Abort on command error.
