This avoids the duplication where the option is stored in a dict at its
name, and also contains its own name. In general, the maxim in
programming is things shouldn't know their own name, so removed the name
field just leaving the option's position in the dictionary as its name.
Also, we should at some point decide whether we're going to use American
spelling (serialize/serialization) or British (serialise/serialisation)
because we have both, and both is always worse than one or the other.
Currently C++ inherits C, which can lead to diamond problems. By pulling
the code out into a standalone mixin class that the C, C++, ObjC, and
Objc++ compilers can inherit and override as necessary we remove one
source of diamonding. I've chosen to split this out into it's own file
as the CLikeCompiler class is over 1000 lines by itself. This also
breaks the VisualStudio derived classes inheriting from each other, to
avoid the same C -> CPP inheritance problems. This is all one giant
patch because there just isn't a clean way to separate this.
I've done the same for Fortran since it effectively inherits the
CCompiler (I say effectively because was it actually did was gross
beyond explanation), it's probably not correct, but it seems to work for
now. There really is a lot of layering violation going on in the
Compilers, and a really good scrubbing would do this code a lot of good.
After the previous commit, outfile is now passed down to lots of things
which don't use it, as they only create built statements, rather than
writing them out. Remove these unnecessary args.
Store the build statements and then write them all out, rather than
writing them out as we go.
Construct a NinjaBuildElement for the 'PHONY' target, rather than
writing it literally to the build.ninja file.
After the previous commit, outfile is now passed down to lots of things
which don't use it, as they only create rules, rather than writing them
out. Remove these unnecessary args.
Store the rules and then write them all out, rather than writing them
out as we go.
Store the rule broken down into parts which do and don't go into
rspfile, so we can construct either a rsp or non-rsp version of the
rule.
Setting this variable to contain additional commands to symlink shlib
aliases was removed in commit c0bf3e8d, so it's always unset now, and
thus does nothing.
This isn't safe given the way python implements default arguments.
Basically python store a reference to the instance it was passed, and
then if that argument is not provided it uses the default. That means
that two calls to the same function get the same instance, if one of
them mutates that instance every subsequent call that gets the default
will receive the mutated instance. The idiom to this in python is to use
None and replace the None,
def in(value: str, container: Optional[List[str]]) -> boolean:
return src in (container or [])
if there is no chance of mutation it's less code to use or and take
advantage of None being falsy. If you may want to mutate the value
passed in you need a ternary (this example is stupid):
def add(value: str, container: Optional[List[str]]) -> None:
container = container if container is not None else []
container.append(value)
I've used or everywhere I'm sure that the value will not be mutated by
the function and erred toward caution by using ternaries for the rest.
This is the VS-specific part of the previous commit; the Visual Studio
backend was ignoring dependencies, add an AdditionalInputs element
similar to what add_custom_build does.
If find_program() returns a file from the source directory, anything
that uses it should add the file to the dependencies, so that they are
rebuilt whenever the script changes. Generator is not doing that.
While at it, I am doing two related fixes:
- Generator is not checking whther the generator actually was found,
resulting in a Python error involving NoneType if it isn't. To minimize
backwards compatibility issues, I am only raising the error when
g.process() is acutally called.
- the error message for custom_target with a nonexisting program
erroneously mention a not-found external program "nonexistingprogram".
The new error is similar to the one I am adding for generators.
Instad of having special casing of threads in the backends and
everywehre else, do what we did for openmp, create a real
dependency. Then make use of the fact that dependencies can now have
sub dependencies to add threads.

inwork compiles OK but needs smod filenames
This patch creates an enum for selecting libtype as static, shared,
prefer-static, or prefer-shared. This also renames 'static-shared'
with 'prefer_static' and 'shared-static' with 'prefer_shared'. This is
just a refactor with no behavioral changes or user facing changes.
Currently we specialcase OpenMP like we do threads, with a special
`need_openmp` method. This seems like a great idea, but doesn't work
out in practice, as well as it complicates the opemp
implementation. If GCC is built without opemp support for example, we
still add -fopenmp to the the command line, which results in
compilation errors.
This patch discards that and treats it like a normal dependency,
removes the need_openmp() method, and sets the compile_args attributes
from the compiler.
