* small cleanups of unused variables in firstpass
* node_resources_fpu() created to get an approximation of the
required fpu registers
* for the moment use node_complexity in the CG until the
node_resource_int() is created
git-svn-id: trunk@8655 -
* rename methodpointerinit/done to callinitblock/callcleanupblock
* moved checks in callnode to separate functions
* funcretnode is now always a simple node instead of a block of
statements
* funcret and methodpointer are generated/optimized only in pass_1 so
a conversion from calln to loadn is much easier
* function result assignments are much more often optimized to use the
assignment destination location instead of using a temp
git-svn-id: trunk@8558 -
perform the transformation of x:=f(hiddencomplexresult, ..)
-> f(x, ...) (the compiler now performs some very
conservative escape analysis for such types)
git-svn-id: trunk@8361 -
finally blocks
* fixed the handling of function results of inlined functions with
exit statements
+ test for the above two issues and for bug fixed in r8091
* copy may_be_in_reg field inside ttempcreatenode.dogetcopy (allows
some more temps which were needlessly forced into memory to be in
registers)
git-svn-id: trunk@8108 -
* fixed some (harmless) ptrint warnings
- removed some commented code in agppcmpw
* added one missing field in a typed constant in cp1251
git-svn-id: trunk@8081 -
* symtables based on TFPHashObjectList and TFPObjectList
* rename torddef.typ to torddef.ordtype
* rename tfloatdef.typ to tfloatdef.floattype
* rename tdef.deftype to tdef.typ
* remove obsolete browser code, browcol is kept so the ide
can still be compiled
git-svn-id: trunk@5192 -
allow runtime optimization if the destination is the
same as a source parameter
* tassignmentnode now sets aktassignmentnode global that can be used
to use the left node as a destination parameter and
skip the assignment
* disabled all cpu specific shortstr concat/append
git-svn-id: trunk@4770 -
* put temps for withnodes and some newnodes in registers
Note: this currently only works because calling ungetregister()
multiple times for the same register doesn't matter. We need again
a way to specify that a register is currently a regvar and as such
should not be freed when you call ungetregister() on it.
