From 19f81d3e33c70c9c902dabaad732e5d33bf05bd4 Mon Sep 17 00:00:00 2001 From: John Ericson Date: Wed, 12 Dec 2018 00:19:03 -0500 Subject: Never access environment.properties downstream Instead use coredata.compiler_options.. This brings the cross and native code paths closer together, since both now use that. Command line options are interpreted just as before, for backwards compatibility. This does introduce some funny conditionals. In the future, I'd like to change the interpretation of command line options so - The logic is cross-agnostic, i.e. there are no conditions affected by `is_cross_build()`. - Compiler args for both the build and host machines can always be controlled by the command line. - Compiler args for both machines can always be controlled separately. --- mesonbuild/compilers/c.py | 22 +++++++++++++++------- 1 file changed, 15 insertions(+), 7 deletions(-) (limited to 'mesonbuild/compilers/c.py') diff --git a/mesonbuild/compilers/c.py b/mesonbuild/compilers/c.py index a591183..b47be7d 100644 --- a/mesonbuild/compilers/c.py +++ b/mesonbuild/compilers/c.py @@ -25,9 +25,9 @@ from .. import mlog from .. import coredata from . import compilers from ..mesonlib import ( - EnvironmentException, MesonException, version_compare, Popen_safe, listify, - for_windows, for_darwin, for_cygwin, for_haiku, for_openbsd, - darwin_get_object_archs + EnvironmentException, MachineChoice, MesonException, Popen_safe, listify, + version_compare, for_windows, for_darwin, for_cygwin, for_haiku, + for_openbsd, darwin_get_object_archs ) from .c_function_attributes import C_FUNC_ATTRIBUTES @@ -427,12 +427,16 @@ class CCompiler(Compiler): # Read c_args/cpp_args/etc from the cross-info file (if needed) args += self.get_cross_extra_flags(env, link=(mode == 'link')) if not self.is_cross: + if env.is_cross_build() and not self.is_cross: + for_machine = MachineChoice.BUILD + else: + for_machine = MachineChoice.HOST if mode == 'preprocess': # Add CPPFLAGS from the env. - args += env.coredata.get_external_preprocess_args(self.language) + args += env.coredata.get_external_preprocess_args(for_machine, self.language) elif mode == 'compile': # Add CFLAGS/CXXFLAGS/OBJCFLAGS/OBJCXXFLAGS from the env - sys_args = env.coredata.get_external_args(self.language) + sys_args = env.coredata.get_external_args(for_machine, self.language) # Apparently it is a thing to inject linker flags both # via CFLAGS _and_ LDFLAGS, even though the former are # also used during linking.
