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'] |
|

def _can_dedup(cls, arg): |

''' |
|
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. |
