Currently only via pragma (not command line options), but I needed to
test the concept. Converting legacy code is just too error prone.
Telling the compiler how to treat the operator makes more sense. When *
acts as @dot with Ruamoko progs, the result is automatically aliased as
a float as this is the legacy meaning (ie, float result for dot
product).
The command line option works the same way as
--advanced/traditional/extended, as does the pragma. As well, raumoko
(alternative spelling) can be used because both are legitimate and some
people may prefer one spelling over the other.
As always, use of the pragma is at one's own risk: its intended use is
forcing the target in the unit tests.
It never really helped sort out the path issues when using build
directories. It worked well enough for single directory projects, but
things got messy very quickly, especially when mixing ruamoko libs with
external progs. A better method based on dwarf is coming.
qfcc now does local common subexpression elimination. It seems to work, but
is optional (default off): use -O to enable. Also, uninitialized variable
detection is finally back :)
The progs engine now has very basic valgrind-like functionality for
checking pointer accesses. Enable with pr_boundscheck 2
After running across a question about lists of animation frames and states,
I decided giving qfcc the ability to generate such lists might be a nice
distraction from the optimizer :) Works for both progs.src and separate
compilation. No frame file is generated if no macros have been created.
The output can be controlled via --block-dot (not yet documented). The
files a named <sourcefile>.<function>.<stage>.dot. Currently, stage will be
one of "initial" (after expression to statement conversion), "thread"
(after jump threading), "dead" (after dead block removal), "final" (final
state before actual code emission).
Despair has things locked down such that running qfcc during a build fails
due to lack of read access to /usr/local/lib. This is actually a good
thing as accidentally hitting old includes/libs (when a file gets deleted
in the tree) hides bugs. Thus, --no-default-paths to turn off default
search paths.
"vector-components" in code options controls this feature. The default is
off for advanced code and on for traditional code. Disabling
vector-components prevents the comonent names polluting the namespace and
reduces the number of globals needed for vector fields if the components
of that field are never used.
