Call hlcg.getlocal instead of tg.getlocal when used for actual parameters/local
variables. Has an extra tsym parameter, which will enable the LLVM backend to
insert debug information.
Call hlcg.recordnewsymloc when the location of a (local/para) symbol changes,
so debug info tracking can be updated (only done for LLVM currently)
their default alignment, the alignment of locals, globals and constants
(so that we don't overestimate the alignment of global normal set
constants to 32 bytes, while the maximum const alignment is often only
8 bytes)

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)

a load node for a procsym has a self pointer, that we have to create
a procvar with a self pointer (e.g. when loading the address of a
static class method). Avoids the generation of superfluous code to
load self which is then not used afterwards
git-svn-id: trunk@35005 -
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 -
and getters for the ttemp*node classes instead
o this will allow descendants to prevent certain flags from being added
or removed. E.g. for LLVM, certain temps must never be put in registers
because it cannot typecast a value in a register from a non-record/array
type to an array type without forcing it to memory (so if that is done
on an lvalue, the result will be written to the memory temp instead of
to the register)
git-svn-id: trunk@34358 -
release the source location in case it was also a temp. Reason: we
don't increase reference counts when assigning to a ti_const (they are
like const parameters), so the original value must stay alive until
the ti_const temp is freed
o free the original data in the ttempdelete node for the ti_const temp
o don't increase reference counts when assigning composite types to
ti_const temps either
git-svn-id: trunk@34287 -
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
git-svn-id: trunk@34250 -
tasmdata.DefineAsmSymbol() and all routines that call it
o will be used to automatically generate AB_INDIRECT sybols when
necessary
