2024-05-14Add /Zc:preprocessor in experimental cxx.std mode from MSVC 17.9 (19.39)Boris Kolpackov1-1/+1
For background, see: https://developercommunity.visualstudio.com/t/Please-clarify-ifwhen-Zc:preprocessor/10537317
2024-05-13Issue better diagnostics if standard library modules not supportedBoris Kolpackov1-142/+150
2024-05-13Update std.cppm to Clang 18, add std.compat.cppmBoris Kolpackov4-80/+1087
Note that Clang 17 is not longer supported with regards to standard library modules.
2024-05-09Fixes and tweaks to diagnostics color support on Windows (GH issue #312)Boris Kolpackov1-1/+13
Specifically: - Pass -fansi-escape-codes for Clang on Windows. - Enable diagnostics color by default if already enabled on the terminal. Only try to enable it ourselves with explicit --diag-color.
2024-05-06Switch from libpkg-config to version from libbutlBoris Kolpackov1-1/+1
2024-02-26Add ability to serialize compilation/linking in cc rulesBoris Kolpackov4-8/+43
Specifically, both the C/C++ compiler and link rules now recognize the cc.serialize boolean variable which instructs them to compiler/link serially with regards to any other recipe. This is primarily useful when compiling large translation units or linking large binaries that require so much memory that doing that in parallel with other compilation/linking jobs is likely to summon the OOM killer. For example: obj{memory-hog}: cc.serialize = true
2024-02-22Detect dependency cycles in *.export.libsBoris Kolpackov1-0/+5
Fixes GH issue #362.
2024-02-22Detect non-cc::link_rule libraries not marked with cc.type=ccBoris Kolpackov1-4/+11
Fixes GH issue #368.
2024-02-22Deal with libs{} being member of group in windows_rpath_timestamp()Boris Kolpackov1-1/+14
Fixes GH issue #366.
2024-02-15Add fsdir{} duplicate suppression in more placesBoris Kolpackov2-2/+9
2024-02-06Fix bunch of maybe used uninitialized warningsBoris Kolpackov2-2/+3
2024-02-02Handle unseparated `rc` and `git` suffixes in Clang version (GH issue #360)Boris Kolpackov1-2/+38
2024-01-29Fix pkgconfig_load() to set common poptions for lib{} target groupKaren Arutyunov1-6/+47
2024-01-11Properly split injected ad hoc group member name in regex pattern ruleBoris Kolpackov1-1/+2
2024-01-10Add ability to specify alternative sysroot for pkg-config files (GC issue #59)Boris Kolpackov2-4/+65
Specifically, the new config.cc.pkgconfig.sysroot variable provides roughly equivalent functionality to PKG_CONFIG_SYSROOT_DIR in pkg-config. For details and limitations, see "Rewriting Installed Libraries System Root (sysroot)" in the manual for details.
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
2024-01-08Handle absent paths in cc::gcc_header_search_dirs() (e.g., due to -nostdinc)Boris Kolpackov1-8/+17

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.
