inline assembly, and fixed check after r35959 (mantis #32318)
o can also subscript parameters passed by value on the stack
o can also subscript local variables, the parameters passed by reference
that are subsequently copied into a local

* changed most of the variables in the assembler readers used to store constants from aint to tcgint
as aint has only the size of the accumular while some CPUs (AVR) allow larger constants in instructions
+ allow access to absolute symbols with address type in inline assembler
* allow absolute addresses in avr inline assembler
+ tests

determine whether it's in a register if it's a pure assembler routine
* you can't "index" implicit pointers either using their fields

directly in inline assembly: that's only possible if it's a register
parameter where the address of the record was passed (rather than the
record itself), or if a parameter has been explicitly typecasted in
Intel-style assembly using ".size"
git-svn-id: trunk@35959 -
ad hoc set constants containing varying number cdecl-like calling
conventions
o added pocall_sysv_abi_cdecl and pocall_ms_abi_cdecl to cstylearrayofconst
o also allow C-style blocks with mwpascal instead of cdecl (mwpascal = cdecl
with "const" = "constref" for record parameters)
o did not touch cases related to name mangling and import/export names,
because those are a real mess and easily break things left and right :/

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.

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 -
symbol is defined
o removed all places where AB_INDIRECT symbols were explicitly generated
o only generate AB_INDIRECT symbols for AT_DATA on systems_indirect_var_imports
o for some symbols an indirect symbol is always required (because they are
dereferenced by code in RTL units) -> use new AT_DATA_FORCEINDIRECT type
git-svn-id: trunk@34165 -
tasmdata.DefineAsmSymbol() and all routines that call it
o will be used to automatically generate AB_INDIRECT sybols when
necessary

whether a multiplication needs to be signed or unsigned (can be different
in case of a 32x32->64 multiplication) (mantis #30035)

* WriteTree: implement the ait_realconst case by calling WriteRealConstAsBytes
* WriteTree: remove commented code handling the old constants

of 2: paraloc^.size was then OS_NO, so their shiftval was set to 0,
while we also have to put those in the upper bytes of the paraloc

"don't free even if not registered"; use for defs that may not be written
to a ppu file, but that must nevertheless survive the compilation of the
current module
* mark all defs created for para locations as "don't free even if not
registered", because we don't discard and recalculate all para locations
after a module has been compiled (since that's not needed)
o solves issues if the paralocations for a routine in the interface of
unit A are calculated while the implementation of unit B gets
compiled, and a new reusable type is allocated at that point which
is not used anywhere else (after r32160)

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)

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).
