that itself, our LLVM code generator can't handle it, and if it did then
afterwards we would have to spill 90% of those register variables again
to make them SSA)

Currently it is implemented only for x86-CPUs supporting the FMA extension. While it would
be possible to implement it in software or simulate fma(<single>,<single>,<single>) using
double operations, it makes no sense in my opinion to do so.
git-svn-id: trunk@27564 -
like field reordering (possible problems cracker classes) or using ebp as normal register (broken
stack traces from dump_stack)
+ niln is also valid in a cse domain
* parameters passed by reference shall have a complexity >1
* load nodes from outer scopes shall have a complexity >1
* better cse debugging
+ more node types added to cse
* consider parameters passed by reference in cse
* take care of cse in parameters in simple cases
git-svn-id: trunk@22050 -
order to minimise memory losses due to alignment padding. Not yet enabled
by default at any optimization level, but can be (de)activated separately
via -Oo(no)orderfields
o added separate tdef.structalignment method that returns the alignment
of a type when it appears in a record/object/class (factors out
AIX-specific double alignment in structs)
o changed the handling of the offset of a delegate interface
implemented via a field, by taking the field offset on demand
rather than at declaration time (because the ordering optimization
causes the offsets of fields to be unknown until the entire
declaration has been parsed)
git-svn-id: trunk@21947 -
the drawback of this is that get_caller_frame and get_caller_addr might not work
anymore because they make the wrong assumption (i.e. not required by the abi)
that ebp contains always a valid (not necessarily the current) frame pointer
git-svn-id: trunk@21918 -
explicitly using -Ooasmcse for now. It will probably be completely
removed before the next major release after 2.4.0 (fixes mantis
#14363)
git-svn-id: trunk@13545 -
(so both can be combined with each other, as well as with other calling
conventions)
* defined COMPPROCINLINEFIXED so SYSTEMINLINE is again activated
git-svn-id: trunk@658 -
+ refaddr to treference added
+ refsymbol to treference added
* top_local stuff moved to an extra record to save memory
+ aint introduced
* tppufile.get/putint64/aint implemented
