2024-01-15Add no_default_target attribute for source, buildfile import directivesBoris Kolpackov2-13/+63
This attribute can be used to disable the default target semantics for the sources/imported buildfile.
2024-01-15Disable default target semantics when loading {bootstrap,root}.buildBoris Kolpackov1-2/+6
2024-01-15Make sure --dump-{scope,target} are specified with --dumpBoris Kolpackov1-0/+12
2024-01-15Automatically alias unknown target types of imported targetsBoris Kolpackov6-47/+140
2024-01-15Fail with unable to import rather than unknown target typeBoris Kolpackov7-25/+140
2024-01-11Add ability to alias target type from another projectBoris Kolpackov3-39/+109
The syntax is: define <type> = <scope>/<type>
2024-01-11Fix name recomposition bug in $name.filter*() functionsBoris Kolpackov2-2/+13
2024-01-11Properly split injected ad hoc group member name in regex pattern ruleBoris Kolpackov5-10/+16
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 abs_dir_path conversion diagnosticsBoris Kolpackov1-1/+8
2024-01-10Fix bunch of typosBoris Kolpackov6-10/+10
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).
2024-01-09Allow imported buildfiles to using config.* variables from own projectBoris Kolpackov3-38/+189
2024-01-08Improve documentation commentBoris Kolpackov1-2/+2
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
2024-01-08Add {bin,c,cxx}.types submodules that only register target typesBoris Kolpackov7-166/+371
2023-12-14Allow enabling C++ modules for C++20 and later std.cxx valuesBoris Kolpackov2-90/+243
2023-12-14Cleanup old code for C++ modules support in ClangBoris Kolpackov1-106/+2
2023-12-13Fix another instance of module name not being assigned due to deferred failureBoris Kolpackov1-10/+17
2023-12-12Work around unexecuted member for installed libraries issueBoris Kolpackov4-21/+64
See comment for the long-term plan.

2023-12-07Fix bug that led to duplication of module import informationBoris Kolpackov1-1/+7
2023-12-07Add support for compiling MSVC standard library modulesBoris Kolpackov1-41/+144
2023-12-07C++20 named modules support for MSVC, take 2Boris Kolpackov7-135/+126
2023-12-04Clarify commentBoris Kolpackov1-4/+4
2023-12-04Don't match predefs rule for unsupported compiler/versionBoris Kolpackov1-1/+24
2023-12-04Improve parser diagnosticsBoris Kolpackov1-1/+5
2023-12-04Support creating file symlinks with ad hoc recipesBoris Kolpackov1-6/+52
2023-12-03Support dir{}/fsdir{} idiosyncrasies in $name.*() function familyBoris Kolpackov1-0/+6
2023-12-03Reimplement search_existing() functions via target_type::searchBoris Kolpackov18-66/+91
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.
2023-12-03Search in src for existing prerequisites with unspecified outBoris Kolpackov5-23/+58
2023-12-03Make fsdir{} usable as target of ad hoc Buildscript recipesBoris Kolpackov2-3/+41
In particular, it can now be used to represent a directory symlink. For example: exe{hello}: ... fsdir{assets} fsdir{assets}: % update {{ ln -s $src_base/assets $out_base/assets }} % clean {{ rm $out_base/assets }}
2023-11-29Add rule for extracting C and C++ predefsBoris Kolpackov8-30/+518
2023-11-29Minor cleanups in cc::compile_ruleBoris Kolpackov1-6/+3
2023-11-29Complete earlier fix for modules support in ClangBoris Kolpackov1-5/+2
2023-11-27Fix minor incompatibility with C++14Boris Kolpackov1-1/+1
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.

2023-11-16Extend comment on Clang's -fmodules-embed-all-files useBoris Kolpackov1-0/+6
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.
