procedures with large numbers of variables:
- added pass-time tracking for pre-cpnanopass passes to compile.
compile.ss
- added inline handler for fxdiv-and-mod
cp0.ss, primdata.ss
- changed order in which return-point operations are done (adjust
sfp first, then store return values, then restore local saves) to
avoid storing return values to homes beyond the end of the stack
in cases where adjusting sfp might result in a call to dooverflood.
cpnanopass.ss, np-languages.ss
- removed unused {make-,}asm-return-registers bindings
cpnanopass.ss
- corrected the max-fv value field of the lambda produced by the
hand-coded bytevector=? handler.
cpnanopass.ss
- reduced live-pointer and inspector free-variable mask computation
overhead
cpnanopass.ss
- moved regvec cset copies to driver so they aren't copied each
time a uvar is assigned to a register. removed checks for
missing register csets, since registers always have csets.
cpnanopass.ss
- added closure-rep else clause in record-inspector-information!.
cpnanopass.ss
- augmented tree representation with a constant representation
for full trees to reduce the overhead of manipulating trees or
subtress with all bits set.
cpnanopass.ss
- tree-for-each now takes start and end offsets; this cuts the
cost of traversing and applying the action when the range of
applicable offsets is other than 0..tree-size.
cpnanopass.ss
- introduced the notion of poison variables to reduce the cost of
register/frame allocation for procedures with large sets of local
variables. When the number of local variables exceeds a given
limit (currently hardwired to 1000), each variable with a large
live range is considered poison. A reasonable set of variables
with large live ranges (the set of poison variables) is computed
by successive approximation to avoid excessive overhead. Poison
variables directly conflict with all spillables, and all non-poison
spillables indirectly conflict with all poison spillables through
a shared poison-cset. Thus poison variables cannot live in the
same location as any other variable, i.e., they poison the location.
Conflicts between frame locations and poison variables are handled
normally, which allows poison variables to be assigned to
move-related frame homes. Poison variables are spilled prior to
register allocation, so conflicts between registers and poison
variables are not represented. move relations between poison
variables and frame variables are recorded as usual, but other
move relations involving poison variables are not recorded.
cpnanopass.ss, np-languages.ss
- changed the way a uvar's degree is decremented by remove-victim!.
instead of checking for a conflict between each pair of victim
and keeper and decrementing when the conflict is found, remove-victim!
now decrements the degree of each var in each victim's conflict
set. while this might decrement other victims' degrees unnecessarily,
it can be much less expensive when large numbers of variables are
involved, since the number of conflicts between two non-poison
variables should be small due to the selection process for
(non-)poison variables and the fact that the unspillables introduced
by instruction selection should also have few conflicts. That
is, it reduces the worst-case complexity of decrementing degrees
from O(n^2) to O(n).
cpnanopass.ss
- took advice in compute-degree! comment to increment the uvars in
each registers csets rather than looping over the registers for
each uvar asking whether the register conflicts with the uvar.
cpnanopass.ss
- assign-new-frame! now zeros out save-weight for local saves, since
once they are explicitly saved and restored, they are no longer
call-live and thus have no save cost.
cpnanopass.ss
- desensitized the let-values source-caching timing test slightly
8.ms
- updated allx, bullyx patches
