2024-01-10Fix bunch of typosBoris Kolpackov4-6/+6
2024-01-09Disable use of -frewrite-includes for assembler with preprocessor filesBoris Kolpackov1-3/+24
With -frewrite-includes Clang has issues with correctly tracking location information (manifests itself as wrong line numbers in debug info, for example). The result also appears to reference the .Si file instead of the original source file for some reason. While at it also omit trying to scan such files since that can be hazardous (such files sometimes use `#`-style comments).
2024-01-08Allow specifying compiler mode options in buildfileBoris Kolpackov1-7/+20
Now the configured mode options are appended to buildfile-specified (which must be specified before loading the guess module). In particular, this ability to specify the compiler mode in a buildfile is useful in embedded development where the project may need to hardcode things like -target, -nostdinc, etc. For example: cxx.std = 20 cxx.mode = -target riscv32-unknown-unknown -nostdinc using cxx

2023-12-03Reimplement search_existing() functions via target_type::searchBoris Kolpackov2-2/+2
This allows us to automatically get the target type-specific behavior with regards to the out_only semantics (added in the previous commit) instead of passing it explicitly from each call site.

2023-11-27Tweak module name from file name guessing logicBoris Kolpackov1-2/+41
As a heuristics, prefer shorter but exact partition name matches to longer but partial.
2023-11-22Fix cc::link_rule and cc::install_rule to recognize S{} even in C++Boris Kolpackov2-20/+20
Failed that, a C++ link rule cannot match a dependency with S{} prerequisites.

2023-11-15Switch from two-step module compilation to -fmodule-output for ClangBoris Kolpackov1-0/+35
2023-11-14Remap Apple Clang 14.0.3 and 15.0.0 to vanilla Clang 14.0 and 15.0Boris Kolpackov1-6/+14
Lately, we started seeing __LIBCPP_VERSION values like 15.0.6 or 16.0.2 which would suggest the base is 15.0.5 or 16.0.1. But that assumption did not check out with the actual usage. For example, vanilla Clang 16 should no longer require -fmodules-ts but the Apple's version (that is presumably based on it) still does. So the theory here is that Apple upgrades to newer libc++ while keeping the old compiler. Which means we must be more conservative and assume something like 15.0.6 is still 14-based.

Also make fsdir_rule::perform_{update,clean}_direct() harder to misuse.
2023-11-01Handle match options for post hoc libs{} prerequisites in cc::install_ruleBoris Kolpackov2-0/+78
2023-11-01Use match options for runtime/buildtime distinction when installing librariesBoris Kolpackov3-67/+393
Specifically, now, if a library is installed solely as a prerequisite of an executable (potentially recursively), then only its runtime files are installed omitting everything buildtime-related (static/import libraries, non-versioned symlinks for shared libraries, pkg-config files, headers, etc). If you are familiar with the runtime and -dev/-devel package splits for libraries in Debian/Fedora, this is an analogous semantics.
2023-11-01Undo "Don't install static library prerequisites of executable"Boris Kolpackov2-26/+1
This turned out not to be always correct since a static library can have prerequisites that it requires at runtime (see the libca-certificates-curl for an example). The new plan is to split static/shared library installation into run-time and build-time parts using the new match options mechanism.

2023-09-11Invoke Clang to produce object files for module partitions similar to interfacesSwat SomeBug1-2/+7
Module interface and implementation partitions are like module interfaces so it's not surprising they require similar compilation steps. See GH PR #328 for background.
2023-09-08Manually extract library search paths from LIBRARY_PATH for ClangBoris Kolpackov4-70/+90
Unlike GCC, Clang does not incorporate the LIBRARY_PATH environment variable value into the -print-search-dirs output.
2023-09-07Search for .tbd in addition to .dylib in Mac OSBoris Kolpackov1-0/+25
Besides .dylib, Mac OS now also has "text-based stub libraries" that use the .tbd extension. They appear to be similar to Windows import libraries and contain information such as the location of the .dylib library, its symbols, etc. For example, there is /Library/.../MacOSX13.3.sdk/usr/lib/libsqlite3.tbd which points to /usr/lib/libsqlite3.dylib (but which itself is invisible/inaccessible, presumably for security). Note that for now we are treating the .tbd library as the shared library but could probably do the more elaborate dance with ad hoc members like on Windows if really necessary.
2023-09-07Add implied .../MacOSX*.sdk/usr/lib/ to system library search directoriesBoris Kolpackov1-7/+22
2023-08-29Add diagnostics color support on Windows (GH issue #312)Boris Kolpackov1-8/+39
Note that currently this has to be enabled with an explicit --diag-color option. In the future the plan is to enable it by default if supported.
2023-08-22Consider *_inc{} target types as headers for rule match purposesBoris Kolpackov5-18/+24
2023-08-22Add abstract c_inc{} and cxx_inc{} target typesBoris Kolpackov2-0/+32
These abstract base target types are meant for deriving additional target types (for example, Qt moc{}) that can be #include'd in C and C++ translation units, respectively. In particular, only such targets will be considered to reverse-lookup extensions to target types (see dyndep_rule::map_extension() for background).
