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 -
{$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 -
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 -
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 -
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 -
"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)
git-svn-id: trunk@32235 -
on the stack, this can be enabled by -OoFORCENOSTACKFRAME. This reduces the required
entry/exit code and makes an extra register available to the compiler. However, since this is
based on an estimation of the required stack size, it might have two drawbacks:
either the stack frame is estimated to big, the program requires a bigger stack than needed
or it is estimated too small, then the compiler throws an internalerror during compilation. These
issues can be overcome as soon as the compiler supports recompiling subroutines if needed.
git-svn-id: trunk@27239 -
contains the tcgsize of the entire parameter rather than only of
what is left (-> calculate it from the remaining parameter length)
git-svn-id: trunk@24776 -
paramgr.pas, tparamanager:
+ add new method "handle_common_ret_in_param"
* extract common code (safecall + record constructor handling) from "ret_in_param" to "handle_common_ret_in_param" and call the latter in "ret_in_param"
[aarch64,arm,avr,i386,x86_64]/cpupara.pas, tCPUparamanager.ret_in_param:
* call "handle_common_ret_in_param" instead of implementing the same check again and again
ncgcal.pas, tcgcallnode.handle_return_value:
* move the check for (record) constructors to "tparamanager.handle_common_ret_in_param"
git-svn-id: trunk@23520 -
that the type of the parameters can be determined automatically
o added compilerproc declarations for all helpers called in the compiler
via their assembler name, so we can look up the corresponding procdef
git-svn-id: trunk@23325 -
getintparaloc + adapted all call sites of getintparaloc. This
led to a number of additional, related changes:
o corrected the type information for some getintparaloc parameters
o don't allocate some intparalocs in cases they aren't used
o changed "const tvardata" parameter into "constref tvardata" for
fpc_variant_copy_overwrite to make pass-by-reference semantics
explicit
o moved a number of routines that now have to call find_system_type()
from cgobj to hlcgobj so that cgobj doesn't have to start depending
on the symtable unit
o added versions of the cpureg alloc/dealloc methods to hlcgobj that
call through to their cgobj counter parts, so we can call save/restore
the cpu registers before/after calling system helpers from hlcgobj
(not implemented in hlcgobj itself, because all basic register
allocator functionality is still part of cgobj/cgcpu)
git-svn-id: trunk@21696 -
* set tcgpara.def for the function return location (field introduced for and
already used by the JVM code generator, required for future hlcg
functionality)
git-svn-id: trunk@21691 -
always points to the previous r7 on the stack (with the saved return
address coming right after it) so that the debugger and crashreporter
can use it for backtraces as specified in the ABI
o changed NR_FRAME_POINTER_REG and RS_FRAME_POINTER_REG from a symbolic
into a typed constant, and added a new method to tprocinfo that can
be used to initialze it (so it can be inited to r7/r11 depending on
the target platform)
* allow using r9 on Darwin, it was only used by the system on iOS up to
2.x, which we no longer support
* prefer using r9 and r12 before r4..r11 on Darwin, because they are
volatile and hence do not have to be saved
git-svn-id: trunk@20661 -
o new eabihf (hard float) abi
o vfpv3_d16 variant of VFP (default variant used by EABI assemblers: VFPv3
with only 16 double registers instead of 32) and pass it to GNU as
o make the odd numbered single precision floating point VFP registers
available for explicit allocation for use by the calling convention
* fixed copy/paste error in stdname of S30 register
-> use -dFPC_ARMHF to create an ARM eabi hard float compiler
(mantis #21554)
