2021-08-12Add ${c,cxx}.deduplicate_export_libs() functionBoris Kolpackov4-0/+154
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 Kolpackov4-230/+106
It turns out this is a lot faster on deeply-dependent libraries like Boost while not having any noticeable differences for "sane" projects.

2021-06-30Move symbol exporting .def file rule to bin.def module, add support for MinGWBoris Kolpackov4-155/+288
The bin.def module is automatically loaded by the c and cxx modules for the *-win32-msvc target architecture. This allows automatically exporting all symbols for all Windows targets using the following setup (showing for cxx in this example): lib{foo}: libul{foo}: {hxx cxx}{**} ... lib{foo}: def{foo}: include = ($cxx.target.system == 'win32-msvc') def{foo}: libul{foo} if ($cxx.target.system == 'mingw32') cxx.loptions += -Wl,--export-all-symbols That is, we use the .def file generation for MSVC and the built-in support (--export-all-symbols) for MinGW. But it is also possible to use the .def file generation for MinGW. In this case we need to explicitly load the bin.def module (which should be done after loading c or cxx) and using the following setup: using bin.def # In root.build. lib{foo}: libul{foo}: {hxx cxx}{**} ... lib{foo}: def{foo}: include = ($cxx.target.class == 'windows') def{foo}: libul{foo}

2021-06-09Fix cxx pattern rule testBoris Kolpackov2-1/+6
2021-06-08Redo low verbosity diagnostic deduction to use scope instead of targetBoris Kolpackov9-51/+38
2021-06-08Get rid of special *{} wildcard target type notation in target type/patternsBoris Kolpackov4-30/+23
Explicit target{} should be used instead. Also, in this context, absent target type is now treated as file{} rather than target{}, for consistency with all other cases.
2021-06-08Implement ad hoc regex pattern rule supportBoris Kolpackov26-381/+1565
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}

2021-05-28Add support for regex-based target type/pattern specific variablesBoris Kolpackov12-222/+583
