The translate-path feature allows for custom path handling, with a
provided rule, on a per target basis. This can be used to support custom
path syntax.
* a feature to control install prefix for install targets
* usable default for install-prefix on Windows
* additional named installation prefixes based on Autotools
* allow users to add named installation directories
* fix named directories <location> handling when requesting a subproject build
* examples for named installation directories
* document named install directories-related functions, make get-package-name more conveninent to users
* feature to allow staging into a location different than active install-prefix
* support for getting relative paths with stage.get-dir
* Follow-up to removed restriction of pch naming on GCC
* Fix pch path conflict on GCC
gcc-pch-generator rewrites target name to a value derived from a header name
and this cases path conflict if multiple pch are created from the same header.
hello.cpp is duplicated in the test for the same reason but for `exe` target --
`exe hello-afx : hello.cpp ;` uses `hello.o` for object file name.
Adds gnu11 (libstdc++ with new ABI) and libc++ values to stdlib feature.
The value gnu was already in use by sun toolset, so this commit sets it as
libstdc++ with old ABI. Adds support for that feature to gcc, clang-linux and
clang-darwin toolsets. Refactors sun toolset to use stdlib feature via toolset
flags.
* add LTO support
Adds lto feature with 2 values: off (the default) and on. The feature
enables link-time optimizations. Also adds support for the feature to
gcc, clang and msvc toolsets.
* add docs for lto feature
* add lto-mode subfeature
* change lto-mode=full to be the default for uniform behaviour
* make lto feature optional
This adds a `b2::system_info` class to obtain available information on
system we are running in. Currently provides CPU counts.
And currently only implemented for macOS.
