Use of defined on aggregates (hashes and arrays) is deprecated.
You should instead use a simple test for size.

This adds copyright verbiage to the Perl scripts. Scripts that are
known to be clean w.r.t. the 2-clause BSD license are given that
license; unclear ones are given the "LGPL for now".

Save a few hundred bytes...
|
|
Compress macros.c by representing macro directives with a single byte.
We can do this because we only use the ASCII character range inside
the standard macro files.
Note: we could save significant additional space by not having a
pointer array, and instead relying on the fact that we sweep
sequentially through the output array.
|
|
"Stealth whitespace" makes it harder to read diffs, and just generally
cause unwanted weirdness. Do a source-wide pass to get rid of it.
|
|
Concentrate compiler dependencies to compiler.h; make sure compiler.h
is included first in every .c file (since some prototypes may depend
on the presence of feature request macros.)
Actually use the conditional inclusion of various functions (totally
broken in previous releases.)
|
|
Use the same crc64 that we already use for the symbol table hash as
the perfect hash function prehash. We appear to get radically faster
convergence this way, and the crc64 is probably *faster*, since the
table likely to be resident in memory.
|
|
Combining arithmetric (add) and bitwise (xor) mixing seems to give
better result than either.
With the new prehash function, we find a valid hash much quicker.
|
|
Declarations that are not at the head is C99 behaviour, but it's
rather pointless for this little piece of code. Fix to work with
older compilers.
|
|
Speed up pptok.c by just doing |= 0x20 instead of calling tolower() for
every character during prehashing. This is good enough for our needs,
since we don't have any tokens containing the characters @ [ \ ] _ nor
any high-bit characters (in which case we'd have to worry about multibyte
anyway.)
|
|
We need to fail if we land in a hole in the pp_directives array, since
we have a noncontiguous enum preproc_token now.
|
|
Further automate the production of preprocessor conditionals. Now the
code automatically folds if/elif and the negatives.
|
|
|
|
Automatically generate macros to test for %if and %elif variants, which
are guaranteed to be correct across future changes.
|
|
Use a perfect hash to look up preprocessor directives, and generate
the preprocessor directive list automatically.
