class CompilerArgs(list):

'''
|
|
Class derived from list() that manages a list of compiler arguments. Should
|
|
be used while constructing compiler arguments from various sources. Can be
|
|
operated with ordinary lists, so this does not need to be used everywhere.
|
|
|
|
All arguments must be inserted and stored in GCC-style (-lfoo, -Idir, etc)
|
|
and can converted to the native type of each compiler by using the
|
|
.to_native() method to which you must pass an instance of the compiler or
|
|
the compiler class.
|
|
|
|
New arguments added to this class (either with .append(), .extend(), or +=)
|
|
are added in a way that ensures that they override previous arguments.
|
|
For example:
|
|
|
|
>>> a = ['-Lfoo', '-lbar']
|
|
>>> a += ['-Lpho', '-lbaz']
|
|
>>> print(a)
|
|
['-Lpho', '-Lfoo', '-lbar', '-lbaz']
|
|
|
|
Arguments will also be de-duped if they can be de-duped safely.
|
|
|
|
Note that because of all this, this class is not commutative and does not
|
|
preserve the order of arguments if it is safe to not. For example:
|
|
>>> ['-Ifoo', '-Ibar'] + ['-Ifez', '-Ibaz', '-Werror']
|
|
['-Ifez', '-Ibaz', '-Ifoo', '-Ibar', '-Werror']
|
|
>>> ['-Ifez', '-Ibaz', '-Werror'] + ['-Ifoo', '-Ibar']
|
|
['-Ifoo', '-Ibar', '-Ifez', '-Ibaz', '-Werror']

|
|
Returns whether the argument can be safely de-duped. This is dependent
|
|
on three things:
|
|
|
|
a) Whether an argument can be 'overridden' by a later argument. For
|
|
example, -DFOO defines FOO and -UFOO undefines FOO. In this case, we
|
|
can safely remove the previous occurrence and add a new one. The same
|
|
is true for include paths and library paths with -I and -L. For
|
|
these we return `2`. See `dedup2_prefixes` and `dedup2_args`.
|
|
b) Arguments that once specified cannot be undone, such as `-c` or
|
|
`-pipe`. New instances of these can be completely skipped. For these
|
|
we return `1`. See `dedup1_prefixes` and `dedup1_args`.
|
|
c) Whether it matters where or how many times on the command-line
|
|
a particular argument is present. This can matter for symbol
|
|
resolution in static or shared libraries, so we cannot de-dup or
|
|
reorder them. For these we return `0`. This is the default.
|
|
|
|
In addition to these, we handle library arguments specially.
|
|
With GNU ld, we surround library arguments with -Wl,--start/end-group
|
|
to recursively search for symbols in the libraries. This is not needed
|
|
with other linkers.

|
|
# -D FOO BAR
