* - fix iconv detection for boost.locale on iOS
* clang-darwin doesn't need --start-group
* clang-darwin doesn't need -lrt
* Also need appletv to have the same exception. `appletv` is another Xcode clang related platform that would have the same limitations.
combined-x86-power seems to be completely unused and combined is used only in darwin toolset for Objective-C compilation which seems to be broken for 4 years because it uses gcc.set-fpic-options which was removed in 12decb3ce6.
Boost has three libraries that mentions architecture=combined, I have checked they will not brake after this change.
Removes code duplication in darwin and clang-darwin toolsets.
Removes undocumented `<flags>` from several toolsets, there is documented `<compileflags>` that should be used instead.
* features: Support values for instruction-set feature to support Xilinx ZYNQ.
This adds several values for instruction-set (with extensions) to
support various ARM processors associated with Xilinx ZYNQ processors.
These instruction sets are used in various combinations for bare-metal
or FreeRTOS configurations.
* gcc: Support values for instruction-set feature for Xilinx ZYNQ.
`ar s` seems to be widely supported for a very long time:
- at least binutils 2.10 (June 2000)
- at least Darwin 8.0 (April 2005)
- since FreeBSD 3.0 (October 1998)
Note: Most of other (non-widely used) toolsets do not call `ranlib` and do not call `ar` with `s` flag either. I have no idea if they are correct or not, so I am not touching them here.
Removed empty rules
Removed PCH suffix override (missed in
Fix clang-pch implementation to actually use pch instead of pth. boostorg/build#368)
Removed PCH file explicit removal before creation (should be tested in pch.py test)
Unified <pch>on and <pch>off compilation actions
* clang-linux: space concat via module global variable
* clang-linux: unify pch and non-pch compilation
* clang-linux: remove overridden pch suffix
Missed in #368
* clang-linux: no need to explicitly delete pch file
* remove empty compile.c/c++.pch rules
* Clang: Use --version instead of -dumpversion
Fixes issue when Clang 8 and below determined as 4.2.1 version.
* Bootstrap and test with versioned toolset
Eliminates need to manual configure toolsets via `user-config.jam` for testing, and allows to pass to `bootstrap.sh` the same toolset string as you would to B2 invocation what eliminates need to specify a custom exec via `--cxx=`.
This adds default/fallback logic to determine the b2 exec absolute path
as possible. It uses the arg0 and current dir or path to construct the
liekliest path.
fixes#25
Features that are narked as 'free' and 'optional' will now be
ignored when the value specified on the command line is
empty. Hence once can specify `cxxflags=` on the command
line without errors. All current "flags" features are now optional.
fixes#5
Specifying the intel-linux compiler in the path would result in failure
because the path to the compiler would never get detected and hence
the path to the compiler libs would also be missing. This fixes the
issue by explicitly computing the absolute path to the compiler exec
always for both already specified and as found in PATH.
fixes#23
Some latest compilers are rather eager intheir warnings. This can cause
problems with the generated grammar code. Hence avoid such warnings when
compiling the grammar parser.
