2022-03-08Update C/C++ headers and ad hoc sources during match by defaultBoris Kolpackov1-19/+50
Essentially, all headers as well as ad hoc headers and sources are now treated by the cc::link_rule as if they had update=match unless explicit update=execute is specified.
2022-03-08Add update=execute special value for cases where it's not defaultBoris Kolpackov1-1/+1
2022-03-07Add support for update=unmatch|match to ad hoc recipesBoris Kolpackov1-4/+6
2022-03-02Add update operation-specific variable with unmatch|match additional valuesBoris Kolpackov1-10/+94
Note that the unmatch (match but do not update) and match (update during match) values are only supported by certain rules (and potentially only for certain prerequisite types). Additionally: - All operation-specific variables are now checked for false as an override for the prerequisite-specific include value. In particular, this can now be used to disable a prerequisite for update, for example: ./: exe{test}: update = false - The cc::link_rule now supports the update=match value for headers and ad hoc prerequisites. In particular, this can be used to make sure all the library headers are updated before matching any of its (or dependent's) object files.

2021-08-12Add ${c,cxx}.deduplicate_export_libs() functionBoris Kolpackov1-0/+86
This function deduplicates interface library dependencies by removing libraries that are also interface dependencies of the specified libraries. This can result in significantly better build performance for heavily interface-interdependent library families (for example, like Boost). Typical usage: import intf_libs = ... import intf_libs += ... ... import intf_libs += ... intf_libs = $cxx.deduplicate_export_libs($intf_libs)
2021-08-09Merge library hashing and collection into single traversal passBoris Kolpackov1-212/+95
It turns out this is a lot faster on deeply-dependent libraries like Boost while not having any noticeable differences for "sane" projects.

This makes sure mixed-language (e.g., C and C++) utility libraries behave as expected.

See GitHub issue #114 for context.

2021-01-30Add std::{map, multimap} to types.hxxBoris Kolpackov1-2/+0
Seeing that std::map is becoming a common Buildfile variable type.

See the config.cxx.translate_include variable documentation in cxx/init.cxx for details.

2020-11-11Add ${c,cxx}.lib_{poptions,libs,rpaths}() functionsBoris Kolpackov1-36/+36
These functions can be used to query library metadata for options and libraries that should be used when compiling/linking dependent targets, similar to how cc::{compile,link}_rule do it. With this support it should be possible to more or less re-create their semantics in ad hoc recipes.
2020-11-05Initial Emscripten supportBoris Kolpackov1-0/+44
- Target: wasm32-emscripten (wasm32-unknown-emscripten). - Compiler id: clang-emscripten (type clang, variant emscripten, class gcc). - Ability to build executables (.js plus .wasm) and static libraries (.a). Set executable bit on the .js file (so it can be executed with a suitable binfmt interpreter). - Default config.bin.lib for wasm32-emscripten is static instead of both. - Full C++ exception support is enable unless disabled explicitly by the user with -s DISABLE_EXCEPTION_CATCHING=1|2. - The bin module registers the wasm{} target type for wasm32-emscripten.
2020-08-12Adjust linker arguments for LTO parallelizationMatthew Krupcale1-0/+54
GCC 10+ and Clang 4+ support controlling the number of LTO threads/jobs used during linking. Use the build2 scheduler to allocate up to the number of hardware threads to the GCC or Clang linker processes when -flto=auto or -flto=thin is specified, respectively. Otherwise, GCC or Clang will attempt to spawn the number of hardware threads detected for each linker process, which could result in up to n^2 linker threads on a CPU with n hardware threads.
2020-07-13Fold translated *.std options into compiler mode optionsBoris Kolpackov1-1/+0
This way they are accessible in ad hoc recipes.

2020-03-20Generate common .pc file in addition to static/staged when installing lib{}Boris Kolpackov1-9/+49
The common .pc file is produced by ignoring any static/shared-specific poptions and splitting loptions/libs into Libs/Libs.private. It is "best effort", in a sense that it's not guaranteed to be sufficient in all cases, but it will probably cover the majority of cases, even on Windows, thanks to automatic dllimport'ing of functions.
2020-03-17Rename all find*(variable) to lookup*(variable)Boris Kolpackov1-6/+6
Now we consistently use term "lookup" for variable value lookup. At some point we should also rename type lookup to binding and get rid of all the lookup_type aliases.
2020-03-10Force hard links inside backlinked DLL assembly directoryBoris Kolpackov1-1/+2
Windows does not allow the manifest file inside to be a symlink for some (probably security) reasons.

2019-11-29Reorder {cc,c/cxx}.{poptions,loptions}Boris Kolpackov1-1/+6
Now it is c/cxx first followed by cc which is the reverse order of coptions since the header/library search paths are examined in the order specified (in contrast to the "last value wins" semantics that we assume for coptions).
