Cary R.	929fbf3507	Merge pull request #1282 from steveicarus/msys2-clang-support MSYS2 clang support	2025-10-20 19:42:30 -07:00
Martin Whitaker	6210c307fa	Update CI scripts to continue testing PLI 1 support.	2025-10-18 20:07:23 +01:00
Martin Whitaker	935910c3c9	Modify VPI test suite to make PLI 1 tests optional.	2025-10-18 20:05:58 +01:00
Martin Whitaker	cf66c64e32	Make support for PLI 1 (libveriuser and cadpli) a config option. PLI 1 was deprecated in 1364-2005, so disable by default and note that it is deprecated in the help text. This works round the problem that the clang linker (lld) in MSYS2 does not support the -r option, so cannot be used to build libveriuser.a.	2025-10-18 20:02:48 +01:00
Martin Whitaker	8e2d543304	Rework makefiles to eliminate the use of dlltool in Windows builds. The clang dlltool is not compatible with the binutils dlltool. However both the clang and binutils linkers support reading the .def file and creating the import library directly, so we no longer need to perform the link in two stages.	2025-10-18 20:00:19 +01:00
Martin Whitaker	10770c9129	Optimise Perl regression test scripts. When redirection operators are included in a command string passed to the system() subroutine, it spawns an intermediate shell to handle the redirection. This is particularly inefficient when running the tests in MSYS2. Creating our own version of system() based on fork() and exec() allows us to handle the redirection directly.	2025-10-17 20:58:05 +01:00
