procoptions even when it's through an array-of-const parameter
* always call create_varargs_paraloc_info() instead of create_paraloc_info()
in the former case, even when no varargs parameters are specified (because
on some platforms even some non-variadic parameters need to be passed
differently, such as on ARM with gnueabihf)

hiding the method name of the wrapped routine
o also add a few more '&' prefixes to the generated wrapper code to
prevent issues when keywords are used as identifiers
git-svn-id: trunk@40634 -
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)
git-svn-id: trunk@38814 -
tcpuparamanager, very similar to the existing get_volatile_registers_XXX. The
new methods are called get_saved_registers_XXX, where XXX is the register
type ("int", "address", "fpu" or "mm")
git-svn-id: trunk@38794 -
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
git-svn-id: trunk@37411 -
determine whether it's in a register if it's a pure assembler routine
* you can't "index" implicit pointers either using their fields
git-svn-id: trunk@36287 -
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 :/

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)
git-svn-id: trunk@35424 -
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.
git-svn-id: trunk@34808 -
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
git-svn-id: trunk@34164 -
whether a multiplication needs to be signed or unsigned (can be different
in case of a 32x32->64 multiplication) (mantis #30035)
git-svn-id: trunk@33539 -
* WriteTree: implement the ait_realconst case by calling WriteRealConstAsBytes
* WriteTree: remove commented code handling the old constants
