+ make use of it in tcgtypeconvnode.second_nothing
+ Xtensa: implementation of a_tcgcpu.a_loadfpu_intreg_reg and tcgcpu.a_loadfpu_reg_intreg
git-svn-id: trunk@46858 -
* 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)

var-parameter, as the size sometimes gets changed in this routine and
high level code generators don't use the location.size but the def

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

labels of LOC_JUMP in the node's location. This generates some extra jumps
for short circuit boolean and/or-expressions if optimizations are off, but
with optimisations enabled the generated code is the same (except for JVM
because the jump threading optimisation isn't enabled there yet).
git-svn-id: trunk@31431 -
hardcoded registers for the most part)
+ added extra g_exception_discard_reason() that can be called when we only
want to get rid of the currently pushed exception reason, and don't have
to load it (so it can do nothing on platforms that don't use push/pop)
git-svn-id: branches/hlcgllvm@28481 -
required for the LLVM support (LLVM parameter support is not yet
included)
* always return the function return loc from a_call*, again as required
for the LLVM support
git-svn-id: branches/hlcgllvm@26992 -
+ x86 targets now directly call procedure variables located in references.
- a_call_ref method removed from tcg and thlcgobj.
git-svn-id: trunk@26666 -
when converting a LOC_JUMP location to a (OS_INT<x<=32)-bit reg location
(the optimization is similar to r26314, but is for non 64-bit destinations).
git-svn-id: trunk@26315 -
when converting a LOC_JUMP location to a 64-bit reg location by only setting
the low OS_INT-sized register to 0 or 1 in the false/true label parts and then
initializing the remaining registers (obtainable via GetNextReg()) to 0 in the
common part after the jumps.
git-svn-id: trunk@26314 -
converting from a LOC_FLAGS or LOC_JUMP location to a 64-bit reg location.
This fixes test/cg/tcnvint1.pp on i8086 after r26301.
git-svn-id: trunk@26312 -
for certain parameter locations in the x86-64 parameter manager)
* full support for vector types in the high level code generator by
translating arraydefs passed to a_*mm*() methods into vector tcgsizes
git-svn-id: trunk@24762 -
to whether the argument is a float type (the check is there to determine
whether def_cgsize() can give us a correct result, which it can for
floating point types but not yet for arrays used as vectors)
