* src/main.c (main): Add "sanitize" to .FEATURES if ASAN is enabled.
* src/expand.c (expand_variable_output): Remember "recursive" setting
in case it's changed by the expansion of the variable.
* src/file.c (rehash_file): If we drop a file from the global 'files'
hash, remember it in rehashed_files. We can't free it because it's
still being referenced (callers will invoke check_renamed()) but
it will be a leak since it's no longer referenced by 'files'.
* src/remake.c (update_file_1): If we drop a dependency, remember it
in dropped_list. We can't free it because it's still being referenced
by callers but it will be a leak since it's no longer referenced as
a prerequisite.
* tests/scripts/functions/guile: Don't run Guile tests when ASAN is
enabled.
* tests/scripts/functions/wildcard: Enabling ASAN causes glob(3) to
break! Don't run this test.
* tests/scripts/features/exec: Valgrind's exec() doesn't support
scripts with no shbang.
* tests/scripts/jobserver: Valgrind fails if TMPDIR is set to an
invalid directory: skip those tests.
* tests/scripts/features/output-sync: Ditto.
* tests/scripts/features/temp_stdin: Ditto.
There is a lot of specialized code for supporting AmigaOS and it has
not been maintained for a number of years. It's highly unlikely that
the latest versions even compile properly on AmigaOS anymore. After
requesting that someone step forward to own the maintenance of the
port in the GNU Make 4.4 release and getting no takers, I removed it.
* NEWS: Announce the removal.
* README.in: Remove README.Amiga reference.
* README.Amiga: Remove unused file.
* SCOPTIONS: Ditto.
* src/amiga.c: Ditto.
* src/amiga.h: Ditto.
* src/config.ami: Ditto.
* mk/Amiga.mk: Ditto.
* Makefile.am: Remove references to deleted files.
* Basic.mk.template: Ditto.
* maintMakefile: Ditto.

Fix .NOTINTERMEDIATE without prerequisites to disable intermediate
status for all targets.
* src/makeint.h: Declare extern no_intermediates.
* src/main.c: Add global definition of no_intermediates.
* src/file.c: Remove static no_intermediates to use global variable.
(remove_intermediates): Check no_intermediates.
* src/implicit.c (pattern_search): For a file found by implicit search
set file->notintermediate if no_intermediates is set.
* src/remake.c (update_file_1): Don't set file->secondary for a
pre-existing file if no_intermediates is set. The check for
no_intermediates here is redundant, but won't hurt: keep it in case
things change so that it matters.
* tests/scripts/targets/NOTINTERMEDIATE: Fix a test.
Don't assume that time_t fits in long, as some hosts (e.g.,
glibc x86 -D_TIME_BITS=64) have 32-bit long and 64-bit time_t.
* bootstrap.conf (gnulib_modules): Add largefile, to support files
with timestamps after Y2038 on hosts with 32-bit long.
* configure.ac: Do not call AC_SYS_LARGEFILE, as the largefile module
does that for us.
* src/makeint.h (PRIdMAX, PRIuMAX, SCNdMAX): Define if not already
defined (taken from gnulib).
* src/ar.c: Include intprops.h, for TYPE_MAXIMUM, as
INTEGER_TYPE_MAXIMUM does not work on time_t without issuing a bunch
of warnings.
(ar_member_date): Check that result is in time_t range.
(ar_member_date_1): Use intmax_t to hold the date.
(ar_glob_match): Ditto.
* src/arscan.c (VMS_function, VMS_function_ret, ar_scan)
(parse_int, ar_scan, ar_member_pos, ar_member_touch)
(describe_member): Convert long int to intmax_t.
* src/file.c (file_timestamp_sprintf): Use intmax_t/uintmax_t instead
of long/unsigned long for values that might be time_t.
* src/arscan.c (ar_member_touch): Fix buffer overrun if the timestamp
is too large.
The next version of the POSIX standard defines parallel execution
and requires the .WAIT special target as is implemented in some other
versions of make.
This implementation behaves similarly to others in that it does not
create a relationship between targets in the dependency graph, so
that the same two targets may be run in parallel if they appear as
prerequisites elsewhere without .WAIT between them.
Now that we support .WAIT it's trivial to also support prerequisites
of the .NOTPARALLEL special target, which forces the prerequisites of
those targets to be run serially (as if .WAIT was specified between
each one).
* NEWS: Announce the new .WAIT and .NOTPARALLEL support.
* doc/make.texi (Parallel Disable): A new section to discuss ways in
which parallel execution can be controlled. Modify cross-refs to
refer to this section.
* src/dep.h (struct dep): Add a new wait_here boolean.
(parse_file_seq): Add PARSEFS_WAIT to check for .WAIT dependencies.
* src/file.c (split_prereqs): Use PARSEFS_WAIT.
(snap_deps): If .NOTPARALLEL has prerequisites, set .WAIT between
each of _their_ prerequisites.
(print_prereqs): Add back in .WAIT when printing prerequisites.
* src/implicit.c (struct patdeps): Preserve wait_here.
(pattern_search): Ditto. Use PARSEFS_WAIT when parsing prereqs for
pattern rule expansion.
* src/read.c (check_specials): Don't give up early: remembering to
update these options is not worth the rare speedup.
(check_special_file): If .WAIT is given as a target show an error--
once--if it has prereqs or commands.
(record_files): Call check_special_file on each target.
(parse_file_seq): If PARSEFS_WAIT is given, look for .WAIT prereqs.
If we see one assume that we are building a struct dep chain and set
the wait_here option while not putting it into the list.
* src/remake.c (update_file_1): If wait_here is set and we are still
running, then stop trying to build this target's prerequisites.
* src/rule.c (get_rule_defn): Add .WAIT to the prerequisite list.
* src/shuffle.c (shuffle_deps): Don't shuffle the prerequisite list
if .WAIT appears anywhere in it.
* tests/scripts/targets/WAIT: Add a test suite for this feature.
Commit 07eea3aa4 `make --shuffle` prevented shuffling prerequisites
that use .SECONDEXPANSION, since shuffle happens before expansion.
This has two problems:
1. No shuffling happens for such prerequisites.
2. Use-after-free when outdated '->shuf' links are used.
Add a reshuffle into expansion phase right after dependency changes.
* src/file.c (expand_deps): Add reshuffle if dependencies change.
* src/shuffle.c (identity_shuffle_array): Fix comment typo.
* tests/scripts/options/shuffle: Add new SECONDEXPANSION test.
Second-expand only the prerequisites of the targets being built.
Defer second-expanding the prerequisites of targets until we need
to decide if they should be built.
* NEWS: Mention the change in behavior.
* doc/make.texi (Secondary Expansion): Document the new behavior.
* src/filedef.h (struct file): Add flag snapped.
(expand_deps): Declare a function to second expand the
prerequisites of a target.
* src/file.c (rehash_file): Merge flag snapped.
(expand_deps): Remove qualifier static. Check flag snapped.
(snap_deps): Remove the loop which performed second expansion for all
targets.
* src/remake.c (update_file_1): Second expand the prerequisites of
the considered target.
* tests/scripts/features/se_explicit: Add tests.
* tests/scripts/features/se_implicit: Ditto.
* tests/scripts/features/se_statpat: Ditto.
* src/makeint.h (stpcpy): Add missing declaration.
* src/amiga.c (MyExecute): Avoid extra strlen using stpcpy.
* src/function.c (func_shell_base): Ditto.
(func_error): Use memcpy() not strcpy() when we know the length.
* src/job.c (construct_command_argv_internal): Use stpcpy().
* src/main.c (main): Ditto.
(define_makeflags): Ditto.
* src/variable.c (print_target_variables): Use memcpy() when we know
the length.
* src/commands.c (set_file_variables): Use mempcpy().
* src/expand.c (variable_buffer_output): Ditto.
* src/file.c (expand_deps): Ditto.
* src/function.c (abspath): Ditto.
(handle_function): Ditto.
* src/implicit.c (pattern_search): Ditto.
* src/job.c (construct_command_argv_internal): Use mempcpy() and
don't add multiple spaces when there are no shell flags.
* src/main.c (decode_env_switches): Use mempcpy() to simplify.
(define_makeflags): Ditto.
* src/variable.c (selective_vpath_search): Ditto.
* src/file.c (rehash_file): Fix warning message.
(rehash_file): Fix comment to match the behavior.
* tests/scripts/features/se_explicit: Fix test.
* tests/scripts/features/mult_rules: Add a new test.
Previously we always used the file->stem value as our stem in
set_file_variables(); when that wasn't correct we had to temporarily
set that value while the function was called, then reset it afterward.
This led to issues (for example when we assumed the stem was a cached
string but it wasn't).
Avoid this by passing in the stem as an argument so that different
values can be provided.
Add tests to verify this.
* src/commands.c (set_file_variables): Take second parameter stem to
relieve the callers of set_file_variables() from setting/restoring
file->stem.
* src/commands.h (set_file_variables): Ditto.
(execute_file_commands): Pass file->stem to set_file_variables().
* src/file.c (expand_deps): Pass d->stem to set_file_variables() and
remove set and restore of file->stem.
* src/implicit.c (pattern_search): Pass stem to set_file_variables()
and remove set and restore of file->stem.
* tests/scripts/features/se_explicit: Add new tests.
* tests/scripts/features/se_implicit: Ditto.
* tests/scripts/features/se_statpat: Ditto.
* tests/scripts/variables/automatic: Ditto.
During normal pattern rule expansion only the first pattern (%) is
expanded; however during secondary expansion all patterns were
expanded. Modify secondary expansion to match the behavior of normal
expansion.
Implementation tweaked by Paul Smith <psmith@gnu.org>
* src/file.c (expand_deps): Don't use subst_expand() which replaces
all % with $*: instead replace only the first one, by hand.
Fix a memory leak where the dep structure was not always freed.
* tests/scripts/features/statipattrules: Use .RECIPEPREFIX not TAB.
Add a series of tests verifying that static pattern rules with and
without secondary expansion both return the same results.
If multiple intermediate files are built together be sure all of them
are removed after make is finished. Continue to ensure that targets
that exist before make starts are not removed even if they appear to be
intermediate.
Add a number of tests to pattern rules to verify this behavior.
* src/filedef.h (struct file): Add a new is_explicit bitfield.
* src/file.c (rehash_file): Merge the is_explicit bit.
(enter_prereqs): Set is_explicit if the file is explicitly mentioned.
* src/implicit.c (pattern_search): Set intermediate on the file if it's
not explicit.
(record_files): Set is_explicit if a file is mentioned as a target.
* src/remake.c (update_file_1): Set secondary on files that already
exist so they won't be removed.
* tests/scripts/features/double_colon: Add a test for double-colon
pattern rules.
* tests/scripts/features/patternrules: Update KGO for tests where more
files are removed.
Add new tests to verify handling removal of intermediate files in the
context of grouped pattern targets.
Support a new special target, .NOTINTERMEDIATE. Any file or pattern
prerequisite of this target will never be considered intermediate.
This differs from .SECONDARY in that .SECONDARY files won't be deleted
but they will still not be built if they are missing.
.NOTINTERMEDIATE files are treated the same way as a target which is
explicitly mentioned in the makefile. This is mostly useful with
patterns; obviously mentioning a target explicitly here is enough in
and of itself to make something not intermediate.
Some adjustments made by psmith@gnu.org

(print_file):
* src/implicit.c (pattern_search): Set notintermediate based on the
pattern.
* tests/scripts/targets/NOTINTERMEDIATE: Add a new test suite.
Initialize the global variable_buffer in main() so that it is never
a null pointer. Then invoking variable_expand("") is never needed:
simply use the variable_buffer pointer when we want to restart the
variable buffer. The main point of this simplification is not to
keep a separate pointer to the beginning of the buffer: this is
dangerous because the buffer may be re-allocated. Instead always
use the variable_buffer pointer itself.
* src/variable.h (initialize_variable_output): Publish.
* src/expand.c (initialize_variable_output): Remove static.
* src/main.c (main): Initialize variable_buffer.
* src/file.c (enter_prereqs): Don't call variable_expand("") and
don't save a separate buffer pointer than might be outdated.
(expand_deps): Ditto.
* src/read.c (record_files): Ditto.
* src/remake.c (library_search): Ditto.
* configure.ac: Try compiling Guile headers: they don't work with C90.
* maintMakefile: Simplify config checks via target-specific variables.
* src/makeint.h: Use ATTRIBUTE rather than defining __attribute__,
as that causes compile issues with system headers.
(ENUM_BITFIELD): Don't use enum bitfields in ANSI mode.
* src/main.c: Use ATTRIBUTE instead of __attribute__.
* src/job.h: Ditto.
* src/file.c: Don't define variables inside for loops.
* src/rule.c: Ditto.
* src/dep.h (SI): Only use static inline in non-ANSI mode.
Initial implementation by Christof Warlich <cwarlich@gmx.de>
* NEWS: Announce the new feature.
* doc/make.texi (Other Special Variables): Document .EXTRA_PREREQS.
* src/dep.h (struct dep): New flag to note extra prereq deps.
* src/filedef.h (expand_extra_prereqs): Declare a function to expand
the value of .EXTRA_PREREQS.
* src/file.c (expand_extra_prereqs): Given a struct variable lookup
of .EXTRA_PREREQS, convert it into a list of deps and for each one
make sure it has a struct file and has the new flag set.
(snap_file): A new function invoked by hash_map that will perform
per-file operations: set up second expansion, intermediate, and also
.EXTRA_PREREQS. Manage circular dependencies by ignoring them.
(snap_deps): Defer per-file operations until the end. Look up the
global .EXTRA_PREREQS and pass it along to snap_file for each file.
* src/implicit.c (struct patdeps): Remember the extra prereqs flag.
(pattern_search): Transfer extra prereqs flag settings into the
matched pattern rule.
* src/rule.h (snap_implicit_rules): Rename count_implicit_rules to
snap_implicit_rules since we now do more than count.
* src/rule.c (snap_implicit_rules): As we walk through all the pattern
rules, add in any global .EXTRA_PREREQS to the dep list. Ensure we
take them into account for the max number of prereqs and name length.
* src/main.c (main): Add extra-prereqs to .FEATURES.
Call the renamed snap_implicit_rules.
* tests/scripts/variables/EXTRA_PREREQS: Add tests.
Create a new variable run_silent to hold the current instance's global
silence setting, allowing silent_flag to represent only whether the -s
option was provided on the command line.
* src/makeint.h: Change silent_flag variable to run_silent.
* src/job.c: Ditto.
* src/remake.c: Ditto.
* src/file.c: Ditto.
* src/main.c: Add a new global variable run_silent.
(decode_switches): After switches are decoded, initialize run_silent.
* tests/scripts/targets/SILENT: Add a test for recursive behavior.
If multiple pattern rules have the same pattern as also-make targets
and we attempt to run them at the same time, we might downgrade the
command state from 'running' to 'deps_running'; this will prevent
that also_make from being considered complete causing make to wait
forever for it to finish.
Ensure that set_command_state never downgrades the state of a target.
* src/file.c (set_command_state): Don't downgrade command_state.
* src/filedef.h (struct file): Document the order prerequisite.
* test/scripts/features/patternrules: Test the behavior.
