If the former, then # each compilation step locks the pdb file for writing, which # is a bottleneck and object files from one target can not be # used in a different target. The latter seems to be the # sensible one (and what Unix does) but there is a catch. If # you try to use precompiled headers MSVC will error out # because both source and pch pdbs go in the same file and # they must be the same. # # This means: # # - pch files must be compiled anew for every object file (negating # the entire point of having them in the first place) # - when using pch, output must go to the target pdb # # Since both of these are broken in some way, use the one that # works for each target. This unfortunately means that you # can't combine pch and object extraction in a single target. # # PDB files also lead to filename collisions. A target foo.exe # has a corresponding foo.pdb. A shared library foo.dll _also_ # has pdb file called foo.pdb. So will a static library # foo.lib, which clobbers both foo.pdb _and_ the dll file's # export library called foo.lib (by default, currently we name # them libfoo.a to avoidt this issue). You can give the files # unique names such as foo_exe.pdb but VC also generates a # bunch of other files which take their names from the target # basename (i.e. "foo") and stomp on each other. # # CMake solves this problem by doing two things. First of all # static libraries do not generate pdb files at # all. Presumably you don't need them and VC is smart enough # to look up the original data when linking (speculation, not # tested). The second solution is that you can only have # target named "foo" as an exe, shared lib _or_ static # lib. This makes filename collisions not happen. The downside # is that you can't have an executable foo that uses a shared # library libfoo.so, which is a common idiom on Unix. # # If you feel that the above is completely wrong and all of # this is actually doable, please send patches. if target.has_pch(): tfilename = self.get_target_filename_abs(target) return compiler.get_compile_debugfile_args(tfilename, pch=True) else: return compiler.get_compile_debugfile_args(objfile, pch=False) def get_link_debugfile_args(self, linker, target, outname): return linker.get_link_debugfile_args(outname) def generate_llvm_ir_compile(self, target, outfile, src): compiler = get_compiler_for_source(target.compilers.values(), src) commands = CompilerArgs(compiler) # Compiler args for compiling this target commands += compilers.get_base_compile_args(self.environment.coredata.base_options, compiler) if isinstance(src, File): if src.is_built: src_filename = os.path.join(src.subdir, src.fname) else: src_filename = src.fname elif os.path.isabs(src): src_filename = os.path.basename(src) else: src_filename = src obj_basename = src_filename.replace('/', '_').replace('\\', '_') rel_obj = os.path.join(self.get_target_private_dir(target), obj_basename) rel_obj += '.' + self.environment.get_object_suffix() commands += self.get_compile_debugfile_args(compiler, target, rel_obj) if isinstance(src, File) and src.is_built: rel_src = src.fname elif isinstance(src, File): rel_src = src.rel_to_builddir(self.build_to_src) else: raise InvalidArguments('Invalid source type: {!r}'.format(src)) # Write the Ninja build command compiler_name = 'llvm_ir{}_COMPILER'.format('_CROSS' if target.is_cross else '') element = NinjaBuildElement(self.all_outputs, rel_obj, compiler_name, rel_src) # Convert from GCC-style link argument naming to the naming used by the # current compiler. commands = commands.to_native() element.add_item('ARGS', commands) element.write(outfile) return rel_obj def get_source_dir_include_args(self, target, compiler): curdir = target.get_subdir() tmppath = os.path.normpath(os.path.join(self.build_to_src, curdir)) return compiler.get_include_args(tmppath, False) def get_build_dir_include_args(self, target, compiler): curdir = target.get_subdir() if curdir == '': curdir = '.' return compiler.get_include_args(curdir, False) def get_custom_target_dir_include_args(self, target, compiler): custom_target_include_dirs = [] for i in target.get_generated_sources(): # Generator output goes into the target private dir which is # already in the include paths list.
