Adds 16 bytes to the 32-bit build. (pdpmake GitHub issue 77) 2025-01-21T09:25:46+00:00 Ron Yorston rmy@pobox.com 2025-01-21T09:25:46+00:00 urn:sha1:89b641cbb52bdc29e7e078c7f1ebcfbe7364ba18 Commit 85bbce87d (make: support GNU/BSD suffixes and inference rules) added code to handle inference rules with arbitrary suffixes. Unfortunately it failed to check for a single-suffix rule in the case where no known suffix was found. Add the necessary code and a test which would have caught the problem. Adds 48 bytes. (pdpmake GitHub issue 72) 2025-01-14T12:22:55+00:00 Ron Yorston rmy@pobox.com 2025-01-14T09:52:58+00:00 urn:sha1:85bbce87d6428fbc6a8bf7126988c4458a033727 The specification of inference rules in POSIX implies that only suffixes starting with a period and containing no other periods are to be considered. In contrast, both GNU and BSD make allow suffixes to contain an arbitrary number of periods, or none at all. Allow this as an extension. Adds 640-816 bytes. (pdpmake GitHub issue 70) 2024-10-20T11:52:42+00:00 Ron Yorston rmy@pobox.com 2024-10-20T11:52:42+00:00 urn:sha1:ef4756eb0994bc25de66cbb04e1752dda217ff5d The POSIX standard allows inference rules to be redefined but not the .DEFAULT rule. There is no explicit exception for .DEFAULT to: Only one target rule for any given target can contain commands. Treat redefinition of a .DEFAULT rule as an error in POSIX mode but allow it as an extension. Also, the code didn't allow an inference rule with dependencies to redefine an existing inference rule. This is no longer the case. Adds 64-96 bytes. 2024-09-10T06:54:16+00:00 Ron Yorston rmy@pobox.com 2024-09-10T06:54:16+00:00 urn:sha1:b4d811aa232df8c7416a14f38a2396b028c35ac9 Commit e90345c10 (make: allow empty commands) rearranged readline() in a way that broke the use of conditionals within the definition of a rule. Add a test case to detect this. Adjust readline() so that conditionals are processed before returning command lines or checking for empty lines and comments. Remove the test for a leading tab in skip_lines(). This allows conditionals in the definition of a rule to be indented with a leading tab. 2024-08-10T09:57:21+00:00 Ron Yorston rmy@pobox.com 2024-08-10T09:17:35+00:00 urn:sha1:770bad1fe3c369da32b53d790a26f82c012666e7 GNU make doesn't allow inference rules or the .DEFAULT target to be used for phony targets. POSIX is unclear on the matter but there doesn't seem to be an explicit prohibition of inference rules or .DEFAULT. Follow the GNU make behaviour as a non-POSIX extension. Adds 48-80 bytes. (pdpmake GitHub issue 56) 2024-08-08T11:24:28+00:00 Ron Yorston rmy@pobox.com 2024-08-08T11:17:54+00:00 urn:sha1:e90345c1048f2c53074a1bd88e7870ee6a452b01 pdpmake didn't allow rules to have empty commands. There are circumstances where this may be useful. Make the following changes: - Add a flag to readline() to indicate the next line is expected to be a command. If this flag is true and the input line starts with a tab return it immediately, thus skipping the check for an empty line or comment line. - In docmds() skip tabs and spaces after a command prefix. If the resulting command is empty don't print it or try to execute it. - In newcmd() allow empty commands. Adds 48-96 bytes. (pdpmake GitHub issue 56) 2024-06-14T11:49:53+00:00 Ron Yorston rmy@pobox.com 2024-06-14T11:49:53+00:00 urn:sha1:edf069ffc299d88c2291c20736bd1463ff030e12 Now that POSIX.1-2024 has been released we can replace all references to the 202X draft standard with 2024. Make this change throughout the code and testsuite. The pragma 'posix_2024' has been added. 'posix_202x' remains as an alias for the same. The 2024 standard is enforced by default in POSIX mode. 2024-06-01T10:07:44+00:00 Ron Yorston rmy@pobox.com 2024-06-01T10:07:44+00:00 urn:sha1:433d9fddde9b66727a5066ffe0e5a776da20a4f1 The test 'Complex chain of macro assignments' relies on recursive macro expansion. This is a POSIX 202X feature, so the test should be moved to the appropriate section of the test script. 2024-05-31T09:27:18+00:00 Ron Yorston rmy@pobox.com 2024-05-31T09:27:18+00:00 urn:sha1:f9d10b2b6314ea2a80515112498aaa919ad81c97 Commit d6b764116 (make: fix detection of target rules) checked for target rules before macro assignments. This failed for some Makefiles generated by autotools because partially defined macros were expanded while testing for a target rule. Revert to checking for macro assignments first, but try to detect if the proposed left hand side of the assignment might form part of a target rule with an inline command. Also handle the case where the ';' separator of the inline command has been obfuscated by putting it in a macro. Saves 128-160 bytes. (GitHub pdpmake issues 31, 44)
