that itself, our LLVM code generator can't handle it, and if it did then
afterwards we would have to spill 90% of those register variables again
to make them SSA)

o fixes several places where there was a check whether something is a
fieldvarsym, but not whether it's an instance rather than a class field
git-svn-id: trunk@43786 -
+ AArch64: support for vX.8b/vX.16b register names
+ support for more than 256 registers in the register dat files
- removed totherregisterset
+ AArch64: use vmov to load immediates if possible
+ AArch64: use eor to clear mm registers

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.
git-svn-id: trunk@42340 -
{$modeswitch arraytodynarray} is active (mantis #35576)
o changed compiler to compile without this modeswitch
o added the modeswitch to a test that depends on it
git-svn-id: trunk@42118 -
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)

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)
git-svn-id: trunk@41420 -
of its own buggy version
o added support to the generic version to override part of the functionality
needed to implement an ARM quirk
git-svn-id: trunk@41335 -
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 -
* disable matching volatile references in the assembler optimisers, so they
can't be removed (more conservative than needed, but better than removing
too many)
o the CSE optimiser will ignore them by default, because they're an unknown
inline node for it
* also removed no longer used fpc_in_move_x and fpc_in_fillchar_x inline node
identifiers from rtl/inc/innr.inc, and placed fpc_in_unaligned_x at the
right place
git-svn-id: trunk@40465 -
hlcgllvm in the uses clause of every unit that calls create_hlcodegen
o prevents dependency cycles that can cause llvm codegen units to init
before the cpu variants, which is bad since the llvm versions have to
override the cpu variants in their init code (+ added checks in the
init code that they are in fact initialised later)
git-svn-id: branches/debug_eh@40410 -
Add typecasts where needed to allow for successful compilation of arm-linux target
with -CriotR options when building the compiler.
git-svn-id: trunk@40314 -
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 -
* disable fix for #33439 during bootstrapping with 3.0.x, as 3.0.x cannot compile the currency division without the fix above
git-svn-id: trunk@38558 -
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
git-svn-id: trunk@37886 -
* 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 -
* compinnr.inc include file converted to a unit
* inline number field size stored in ppu increased from byte to longint
* inlines in the parse tree (when written with the -vp option) now printed with
their enum name, instead of number

The linker will always change BL to BLX if necessary, but not vice versa (linker version dependent).
"BLX label" ALWAYS changes the instruction set. It changes a processor in ARM state to Thumb state,
or a processor in Thumb state to ARM state.
git-svn-id: trunk@36086 -
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 -
- all reg allocs and PIC labeels before the instruction;
- all reg deallocs and reg syncs after the instruction.
It fixes bug #31135.
git-svn-id: trunk@35545 -
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 :/
git-svn-id: trunk@35479 -
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
git-svn-id: trunk@34996 -
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
