procedure node_change_local_switch(p : tnode;cs : tlocalswitch;enable : boolean);
to add/remove cs local switch from all p tnode tree localsettings.
modify second_prefetch implementation in arm, ppcgen and x86 subdirectories
to use node_change_local_settings to temporarily disabled
checkpointer local switch, as prefetch is allowed even on unaccessible addresses.
(previous code was buggy because I frogot that each node has it own localswitches).

it was AT_NONE, which is invalid and should never be used
* explicitly pass the correct value for all calls to those methods elsewhere
in the compiler

tasmdata.DefineAsmSymbol() and all routines that call it
o will be used to automatically generate AB_INDIRECT sybols when
necessary
git-svn-id: trunk@34164 -
moved the code to create the procedure start/end etc. that was at the
call sites of g_external_wrapper() into the new g_external_wrapper()
-> got rid of the x86-specific code in expunix, and fixed expunix for
llvm (e.g. tests/test/tlib1{a,b})

already in a register, as this changes the result location into a size
different from what resultdef says (and only in that specific case)
o modified the ppc code so that it always forces a setelementn to uinttype,
as that is the size that is expected by the operations later on

GNU as from binutils for Darwin, and Apple's "as" is based on an old
version of GNU as)
o this will not cause any backward compatibility problems, as the
previous identifier for as_darwin was "AS-Darwin" and the compiler
compared the uppercase value of the -A parameter to the identifier,
so it was not explicitly selectable earlier. The new name is "AS",
so it is explicitly selectable via -Aas like on other platforms.

that we can use assembler writers with different conventions from the
currently set target_asm (e.g. an x86 assembler writer for inline assembly
in LLVM IR)
git-svn-id: trunk@31628 -
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 -
something without a location at all; it's a hint/optional operation,
so if there's nothing to prefetch just don't do anything
(mantis #27811)
git-svn-id: trunk@30502 -
* generate code to load the TOC register if it's required, and
emit the the ".localentry" directive to indicate to the linker
where the actual function body starts
* support the ".localentry" directive in the ppc64 assembler reader
o disable the fpc_qword_to_double() assembler implementation for
ELFv2, because we can't manually insert the .localentry directive
before the stack allocation code
* perform indirect calls on ppc64 via R12 in ncgcal, as R12 needs to
contain the function address on entry on ppc64/ELFv2 (and it's
a volatile register, so there's no problem with always using
it)
git-svn-id: trunk@30198 -
names, and disabled them for ppc64 ELFv2
* disabling those also disables the function descriptors, so use the
_CALL_ELF compiler variable to check whether there is in fact a
function descriptor
git-svn-id: trunk@30196 -
the stack pointer during the prolog. This was done previously in
tcg.g_proc_entry(), but that routine is called after register allocation
and hence has no influence. Also cleaned up the deallocation of that
register by moving the previously ifdef'd code to thlcgppcgen
(mantis #27634)
git-svn-id: trunk@30164 -
* force the left operand into a register if both the left and
right are constants (can happen because not all set add-nodes
are handled in taddnode.simplify) because the code below
expects at least one register operand. Fixes the compilation of a.o.
taddset2 with -O3 on ppc (constant propagagation -> 2 constant
operands)
