* Fix bs-nl handling, exit and Environment for VMS.John Malmberg2015-01-271-12/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fix required a complete rewrite of the command parser vmsjobs.c child_execute_job. The old parser had too many incorrect assumptions about DCL commands and could not be repaired to extended. The parser now more closely parses VMS commands and handles quoted commands and redirection. Command File mode has been improved, but can not fully support bs-nl syntax. VMS Unix shell simulation has been improved. * commands.c: vms_comma_separator is now a run-time setting. * function.c: vms_comma_separator is now a run-time setting. * function.c(func_basename_dir) now reports "[]" or "./" based on VMS crtl runtime setting. * job.c(start_job_command): VMS Handle empty commands propery. * main.c: Add VMS environment variables for run-time settings. * vms_legacy_behavior - Force older behavior. * vms_comma_separator - Commas or spaces for separators. * vms_unix_simulation - Enhanced Posix shell simulation features. * Detect if VMS CRTL is set to report Unix paths instead of VMS. * ':' and '>' are also MAP_DIRSEP on VMS. * makeint.h: Add VMS run-time option variables. * readme.vms: Update to current behavior. * variable.c(define_variable_in_set): Fix VMS Environment variable lookup. * variable.c(define_automatic_variables): Remove some VMS specific automatic variables and use the Unix ones instead. * vms_export_symbol.c: Set max symbol size correctly. * vmsjobs.c: child_execute_job() complete rewrite of VMS comand parsing. * vmsjobs.c(build_vms_cmd): VMS commmand building with shell simulation.

* Create a character map to use for locating stop-points in strings.Paul Smith2013-06-221-1/+1
| | | | | | | | | In various places we were passing flags and characters to compare, then using complex conditionals to see where to stop in string searches. Performance numbers reveal that we were spending as much as 23% of our processing time in these functions, most of it in the comparison lines. Instead create a character map and use a single bitwise comparison to determine if this is any one of the stop characters.

| | | | | | | If -R is set in the makefile and not the command line, then go through all the default variables and undefine them. If -r is set in the makefile and not in the command line, then remove all .SUFFIX prefixes (unless the user set it) and SUFFIX variable setting. In -p mode don't print builtins.

| | | | | | | | | Allows the user to reset the prefix character for introducing recipe lines from the default (tab) to any other single character, and back again. Also, reworked the manual to consistently use the word "recipe" to describe the set of commands we use to update a target, instead of the various phrases used in the past: "commands", "command lines", "command scripts", etc.

| | | | | | | | | | | | | | | string into the strcache. As a side-effect, many more structure members and function arguments can/should be declared const. As mentioned in the changelog, unfortunately measurement shows that this change does not yet reduce memory. The problem is with secondary expansion: because of this we store all the prerequisites in the string cache twice. First we store the prerequisite string after initial expansion but before secondary expansion, then we store each individual file after secondary expansion and expand_deps(). I plan to change expand_deps() to be callable in either context (eval or snap_deps) then have non-second-expansion targets call expand_deps() during eval, so that we only need to store that dependency list once.
* Fix from Eli for incorrect value of $(MAKE) on Cygwin.Paul Smith2006-11-181-1/+1
| | | | | | | | | | | | | | | | A few changes from char* to void* where appropriate, and removing of unnecessary casts. Much more work on const-ifying the codebase. This round involves some code changes to make it correct. NOTE!! There will almost certainly be problems on the non-POSIX ports that will need to be addressed after the const changes are finished: they will need to be const-ified properly and there may need to be some changes to allocate memory, etc. as well. The next (last?) big push for this, still to come, is const-ifying the filenames in struct file, struct dep, etc. This will allow us to store file names in the string cache and finally resolve Savannah bug #15182 (make uses too much memory), among other advantages.

* Fix for bug #1276: Handle SHELL according to POSIX requirements.Paul Smith2004-11-281-9/+17
| | | | | | | | | | | POSIX requires that the value of SHELL in the makefile NOT be exported to sub-commands. Instead, the value in the environment when make was invoked should be passed to the environment of sub-commands. Note that make still uses SHELL to _run_ sub-commands; it just doesn't change the value of the SHELL variable in the environment of sub-commands. As an extension to POSIX, if the makefile explicitly exports SHELL then GNU make _will_ use it in the environment of sub-commands.
