2021-07-22Adjust Emscripten Clang version to account for unreleased snapshotsBoris Kolpackov1-1/+17
2021-07-20Map Apple Clang version 12.0.5 to vanilla Clang 10.0.0Boris Kolpackov1-16/+19
2021-07-01Handle GCC versions in 9.2-win32 form (GitHub issue #156)Boris Kolpackov1-25/+19
2021-06-08Implement ad hoc regex pattern rule supportBoris Kolpackov1-1/+1
An ad hoc pattern rule consists of a pattern that mimics a dependency declaration followed by one or more recipes. For example: exe{~'/(.*)/'}: cxx{~'/\1/'} {{ $cxx.path -o $path($>) $path($<[0]) }} If a pattern matches a dependency declaration of a target, then the recipe is used to perform the corresponding operation on this target. For example, the following dependency declaration matches the above pattern which means the rule's recipe will be used to update this target: exe{hello}: cxx{hello} While the following declarations do not match the above pattern: exe{hello}: c{hello} # Type mismatch. exe{hello}: cxx{howdy} # Name mismatch. On the left hand side of `:` in the pattern we can have a single target or an ad hoc target group. The single target or the first (primary) ad hoc group member must be a regex pattern (~). The rest of the ad hoc group members can be patterns or substitutions (^). For example: <exe{~'/(.*)/'} file{^'/\1.map/'}>: cxx{~'/\1/'} {{ $cxx.path -o $path($>[0]) "-Wl,-Map=$path($>[1])" $path($<[0]) }} On the left hand side of `:` in the pattern we have prerequisites which can be patterns, substitutions, or non-patterns. For example: <exe{~'/(.*)/'} file{^'/\1.map/'}>: cxx{~'/\1/'} hxx{^'/\1/'} hxx{common} {{ $cxx.path -o $path($>[0]) "-Wl,-Map=$path($>[1])" $path($<[0]) }} Substitutions on the left hand side of `:` and substitutions and non-patterns on the right hand side are added to the dependency declaration. For example, given the above rule and dependency declaration, the effective dependency is going to be: <exe{hello} file{hello.map>: cxx{hello} hxx{hello} hxx{common}
2021-05-13Rename sys_inc_dirs to sys_hdr_dirs for consistencyBoris Kolpackov1-8/+8

Their presence is incompatible with what we are doing.

2021-04-22Add another hash/save_environment() overloadBoris Kolpackov1-2/+2
2021-04-07Register environment variables for hermetic build configurationsBoris Kolpackov1-5/+102
2021-03-13Tighten Clang detection not to misdetect GCC built with ClangBoris Kolpackov1-1/+8
GitHub issue #136.
2021-01-30Add std::{map, multimap} to types.hxxBoris Kolpackov1-1/+0
Seeing that std::map is becoming a common Buildfile variable type.
2021-01-30Rework include translation supportBoris Kolpackov1-0/+175
See the config.cxx.translate_include variable documentation in cxx/init.cxx for details.

2020-11-30Add version mapping for Apple Clang 12.0.0Boris Kolpackov1-1/+3
2020-11-05Initial Emscripten supportBoris Kolpackov1-132/+266
- 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.
2020-08-24Use representation when passing target_triplet as hintBoris Kolpackov1-1/+1

2019-11-05Add support for supplying MSVC IFCPATH equivalentBoris Kolpackov1-4/+24
2019-10-31Update comment on Apple Clang to vanilla Clang version mappingBoris Kolpackov1-15/+14
2019-10-19Add find_stem() utility functionBoris Kolpackov1-23/+4
2019-10-18Add ability to specify "compiler mode" options as part of config.{c,cxx}Boris Kolpackov1-30/+97
Such options are (normally) not overridden by buildfiles and are passed last (after cc.coptions and {c,cxx}.coptions) in the resulting command lines. They are also cross-hinted between config.c and config.cxx. For example: $ b config.cxx="g++ -m64"
2019-10-17Derive msvc_cpu from cl.exe signature rather than pathBoris Kolpackov1-41/+29
2019-10-17Add support for VS search by cl.exe path in find_msvc()Karen Arutyunov1-48/+93
2019-10-17Add temporary fallback to x64 in find_msvc()Boris Kolpackov1-3/+8
2019-10-16Make target CPU part of msvc_info structBoris Kolpackov1-18/+21
2019-10-16Try to find MSVC installation for absolute cl.exe pathsBoris Kolpackov1-48/+102
Without this extra logic recursive invocation of the build system (e.g., in tests) will fail to obtain the full environment.
2019-10-14Fix bug in guess_msvc()Karen Arutyunov1-1/+1
2019-10-14Add missing #ifndef BUILD2_BOOTSTRAP around find_msvc() callBoris Kolpackov1-0/+2
2019-10-14Implement MSVC installation discovery for version 15 (2017) and laterKaren Arutyunov1-81/+564
In particular, this removes the requirement to build from the Visual Studio command prompt. Note that since MSVC compiler binaries are target-specific (i.e., there are no -m32/-m64 options nor something like /MACHINE), in this case we default to a 64-bit build (a 32-bit build can still be achieved by running from a suitable command prompt). Finally, this mechanism is also used to find Clang bundled with MSVC.
2019-10-11Various fixes to make clang-cl workBoris Kolpackov1-1/+1
Note that clang-cl's /showInclude output differs from cl's in the face of missing headers. In particular, it does not issue C1083 that we expect. As a result, this part of clang-cl's support is currently non-functional (the rest seems to work, however).
2019-10-11Switch clang-apple to primary/variant version setupBoris Kolpackov1-1/+58
2019-10-11Add support for clang-clBoris Kolpackov1-137/+241
The compiler type is `msvc`, variant `clang`.
2019-10-10Add %VCINSTALLDIR%\Tools\Llvm\bin as fallback search directory for ClangBoris Kolpackov1-6/+28
2019-10-08Pass MSVC and Platform SDK bin\ directories as binutils search pathsBoris Kolpackov1-16/+39
2019-10-08Redo bin pattern as PATH-like search paths rather than fallback directoryBoris Kolpackov1-6/+5
Also, unlike the fallback directory, the search paths are searched first rather than last.
2019-10-07Rearrange options for consistencyBoris Kolpackov1-1/+1
2019-10-07Pass MSVC system library search paths to linker if LIB envvar is unsetBoris Kolpackov1-4/+40
