private_extern (or plain global in case of PECOFF, as the effect is
the same there): visible across object files, but they become local
when linked into a binary/library. This enables cross-unit inlining
of functions accessig implementation-only symbols.

so it also works for 32 bit targets and a high level code generator
(where aint is still 32 bit, but 64 bit operations are not decomposed)

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)

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

This unit was empty unless OLDREGVARS macro was set,
but this does not compile and no change has been made since 2011.
* Remove regvars from all _USES clauses.

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).
git-svn-id: trunk@34576 -
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

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})
git-svn-id: trunk@34131 -
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.
git-svn-id: trunk@31806 -
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)
