* changed the way OP_NEG and OP_NOT are handled in op_reg_ref, in order to be
consistent with op_reg_reg
* introduced op_reg,op_ref,op_subsetreg,op_subsetref and op_loc for the unary
operations only (OP_NEG,OP_NOT)
git-svn-id: trunk@45302 -
* disable matching volatile references in the assembler optimisers, so they
can't be removed (more conservative than needed, but better than removing
too many)
o the CSE optimiser will ignore them by default, because they're an unknown
inline node for it
* also removed no longer used fpc_in_move_x and fpc_in_fillchar_x inline node
identifiers from rtl/inc/innr.inc, and placed fpc_in_unaligned_x at the
right place
git-svn-id: trunk@40465 -
so that they can still be freed after the reference has been changed
(e.g. in case of array indexing or record field accesses) (mantis #33628)
git-svn-id: trunk@38814 -
* compinnr.inc include file converted to a unit
* inline number field size stored in ppu increased from byte to longint
* inlines in the parse tree (when written with the -vp option) now printed with
their enum name, instead of number

less-than-64-bit CPUs that have a 64-bit OP_SHR/OP_SHL/OP_SAR implementation
in their cg64 backend code generator. This is enabled only for i386 for now.
git-svn-id: trunk@36022 -
be used (TBD in a future commit) for optimizing x:=-x and x:=not x on CPUs
that support performing these operations directly in memory (such as x86)
git-svn-id: trunk@35749 -
op=and/or/xor). They generate more optimal code on certain architectures
(including x86). The new inline nodes aren't generated by the compiler yet,
but will be used in the future, at certain optimization levels, whenever the
pattern x:=x op y is detected by the compiler.
git-svn-id: trunk@35666 -
o separate information for reading and writing, because e.g. in a
try-block, only the writes to local variables and parameters are
volatile (they have to be committed immediately in case the next
instruction causes an exception)
o for now, only references to absolute memory addresses are marked
as volatile
o the volatily information is (should be) properly maintained throughout
all code generators for all archictures with this patch
o no optimizers or other compiler infrastructure uses the volatility
information yet
o this functionality is not (yet) exposed at the language level, it
is only for internal code generator use right now
git-svn-id: trunk@34996 -
alignment of the resultdef rather than to 0 (required for llvm, and
cleaner since then the code generator knows the actual alignment)
git-svn-id: trunk@34296 -
loadvmtaddr and vmt_def
o give an error when trying to use sizeof on a class/object when
targeting the JVM (can't get/load the data size there)
git-svn-id: trunk@32764 -
sinttype (they're the same on most platforms, except on 8 bit ones where
ossinttype is still 16 bit)
* simplified and documented second_length(), and fixed some (harmless)
errors in the used tcgsize for the resultdef (it had to be OS_SINT
rather than OS_INT -- now it's just def_cgsize(resultdef) so it's
always correct)

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.
