2021-11-30Add support for dynamic dependencies as byproduct of script bodyBoris Kolpackov1-16/+22
Specifically, the `depdb dyndep` builtin now has the --byproduct option (which must come first). In this mode only the --file input is supported. For example: obje{hello.o}: cxx{hello} {{ o = $path($>) t = $(o).t depdb dyndep --byproduct --what=header --default-type=h --file $t diag c++ ($<[0]) $cxx.path $cxx.poptions $cc.poptions $cc.coptions $cxx.coptions $cxx.mode -o $o -MD -MF $t -c $path($<[0]) }} Naturally, this mode does not support dynamic auto-generated prerequisites. If present, such prerequisites must be specified statically in the buildfile. Note also that the --default-prereq-type option has been rename to --default-type.
2021-11-28Avoid unnecessary work in depdb::close() if using static check_mtime()Boris Kolpackov1-1/+1
2021-11-28Generalize depdb::touch functionality to support custom timestampBoris Kolpackov1-1/+1
2021-11-23Add support for dynamic dependencies in ad hoc Buildscript recipesBoris Kolpackov1-725/+123
Specifically, add the new `depdb dyndep` builtin that can be used to extract dynamic dependencies from a program run or a file. For example: obje{hello.o}: cxx{hello} {{ s = $path($<[0]) depdb dyndep $cxx.poptions $cc.poptions --what=header --default-prereq-type=h -- $cxx.path $cxx.poptions $cc.poptions $cxx.mode -M -MG $s diag c++ ($<[0]) o = $path($>) $cxx.path $cxx.poptions $cc.poptions $cc.coptions $cxx.coptions $cxx.mode -o $o -c $s }} Currently only the `make` dependency format is supported.

2021-08-09Merge library hashing and collection into single traversal passBoris Kolpackov1-2/+2
It turns out this is a lot faster on deeply-dependent libraries like Boost while not having any noticeable differences for "sane" projects.

2020-11-11Add ${c,cxx}.lib_{poptions,libs,rpaths}() functionsBoris Kolpackov1-24/+35
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 Kolpackov1-237/+286
- 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.

2020-07-17Use -fexternc-nounwind by default for Clang targeting MSVCBoris Kolpackov1-5/+27
This option implements the 'c' part in /EHsc and is not a mere optimization; see Clang bug #45021 for details.
