in LOC_CMMREGISTER, not in LOC_CFPUREGISTER (and they also are there in
case the softfp calling convention is used), and this change broke SPARC
git-svn-id: trunk@20667 -
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)
git-svn-id: trunk@20660 -
in code and not in constants. In the case of primitive types constant nodes
are used while complex types like arrays, records and objects use a local
variable which is initialized to zero once at the entry of the method (the
variable is reused if Default() is used for the same type multiple times in
the same method). For this a new compilerproc was added which uses FillChar
to initialize the given memory area to zero.
This fixes Mantis #9420.
+ psystem.pas: Added Default symbol to system unit
+ htypechk.pas: Added function "is_valid_for_default" which checks recursively
whether the given type can be used with Default at all.
Forbidden types are files, helpers, ObjC and C++ types. This
check is used for records, arrays and objects only if the mode
is a non-Delphi one, as Delphi ignores these types on lower
levels.
+ msg/errore.msg: Added error message for unsupported types for Default()
+ symconst.pas: Added a new enum value vo_is_default_var which is used for the
local variables utilized by Default() so their initalization
and finalization can be avoided.
+ pexpr.pas: Add handling of Default() intrinsic to "statement_syssym"
+ ninl.pas: Extended tinlinenode by a method which returns the correct node for
a Default() and used that method in handle_typecheck.
* ncgutil.pas: Check for new flag "vo_is_default_var" when initializing and
finalizing local variables.
* ppu.pas: increase PPU version
+ psub.pas:
* Added a new routine which zeros defaultvars of a symtable.
* Use this routine inside "initializevars".
* Also use this routine to initialize the staticsymtable of the unit/program.
* Adjusted ppudump, because of the new enum value.
+ Added implementation of fpc_zeromem to system unit.
+ Added tests for Default()
git-svn-id: trunk@20629 -
* Modified fpc_ansistr_decr_ref and fpc_widestr_decr_ref so they always zero the pointer passed by reference. Other _decr_ref helpers already do it.
- Removed tcg.g_decrrefcount, calling cg.g_finalize instead.
- finalize_data_node and tcg.g_finalize: removed code generation for zeroing locations, because it is now done by RTL helpers. This further reduces code size.
As a total result of this change and r20118, the size of Lazarus executable is reduced by about 12%.
git-svn-id: trunk@20119 -
* converts the embedded information into controller specific records (arm and avr)
* new cpu-specific units for several Stellaris (Fury and Tempest class) targets,
+ STM32F103RB
- old Stellaris unit has been removed
git-svn-id: trunk@18848 -
* Do not initialize unused symbols, because finalization code is not generated for them either.
* Always initialize/finalize such constants, even if they are declared in {$J-} state and cannot be modified by user code.
git-svn-id: trunk@18121 -
+ parsing of section directive for variables
+ section test
+ write section names in the assembler/binary writers correctly
* allow section only after ; and for embedded targets
git-svn-id: branches/usersections@17154 -
* Unified fpc_initialize_array,fpc_finalize_array with fpc_decref_array and fpc_addref_array by removing 'size' parameter from the former two. Element size is easily calculated from RTTI, so omitting it simplifies code generation. All four helpers are now callable by tcg.g_array_rtti_helper().
* ncgutil.pas: initialization of open array out-parameters is now done properly (using fpc_initialize_array).
+ Test

and no language features requiring initialization are used,
do not initialize units, but just configure the fpu and
signal handlers.
git-svn-id: trunk@16124 -
compiler assumes it remains a sec_code (fixes linking problems with the
iOS SDK 3.2 simulator tool chain when using debug info)
git-svn-id: trunk@16119 -
be used outside the code generator
* renamed tabstractprocdef.requiredargarea into callerargareasize,
and also added calleeargareasize field; added init_paraloc_info(side)
method to init the parameter locations and init those size fields and
replaced all "if not procdef.has_paraloc_info then ..." blocks with
procdef.init_paraloc_info(callersize)"
* moved detection of stack tainting parameters from psub to
symdef/tabstractprocdef
+ added tcallparanode.contains_stack_tainting_call(), which detects
whether a parameter contains a call that makes use of stack paramters
* record for each parameter whether or not any following parameter
contains a call with stack parameters; if not, in case the current
parameter itself is a stack parameter immediately place it in its
final location also for use_fixed_stack platforms rather than
first putting it in a temporary location (part of mantis #17442)
* on use_fixed_stack platforms, always first evaluate parameters
containing a stack tainting call, since those force any preceding
stack parameters of the current call to be stored in a temp location
and copied to the final location afterwards
git-svn-id: trunk@16050 -
+ support for nested procedural variables:
o activate using {$modeswitch nestedprocvars} (compatible with all
regular syntax modes, enabled by default for MacPas mode)
o activating this mode switch changes the way the frame pointer is
passed to nested routines into the same way that Delphi uses (always
passed via the stack, and if necessary removed from the stack by
the caller) -- Todo: possibly also allow using this parameter
passing convention without enabling nested procvars, maybe even
by default in Delphi mode, see mantis #9432
o both global and nested routines can be passed to/assigned to a
nested procvar (and called via them). Note that converting global
*procvars* to nested procvars is intentionally not supported, so
that this functionality can also be implemented via compile-time
generated trampolines if necessary (e.g. for LLVM or CIL backends
as long as they don't support the aforementioned parameter passing
convention)
o a nested procvar can both be declared using a Mac/ISO Pascal style
"inline" type declaration as a parameter type, or as a stand-alone
type (in the latter case, add "is nested" at the end in analogy to
"of object" for method pointers -- note that using variables of
such a type is dangerous, because if you call them once the enclosing
stack frame no longer exists on the stack, the results are
undefined; this is however allowed for Metaware Pascal compatibility)
git-svn-id: trunk@15694 -
- sort of reverted r14134, which is no longer required after the above
change (new_section() inserts the alignment itself)
* made the tai_section.create() constructor private so it cannot be
called directly anymore
git-svn-id: trunk@15482 -
(the ABIs that prescribe special treatment for aggregates with one
scalar element don't either, since a "union containing a single scalar"
is not the same as a scalar)
* fixed passing record with a single float field on PowerPC/AIX abi's
* several changes to cgobj and ncgutil to correctly deal with transfering
such records between integer and floating point registers
git-svn-id: trunk@15416 -
x86-64 platforms (except for win64, which uses another ABI and which
already complied to it) + test
* fixed returning records containing 1 single or double field on darwin/i386,
these have to be returned via ST0 instead of as a regular record
* added support for LOC_FPUREGISTER and LOC_MMREGISTER in several places
where they can now occur due to the previous two changes
* made a few internalerrors unique
git-svn-id: trunk@15368 -
represent complex locations (required for full x86-64 ABI support,
which is not yet implemented) -> lots of special result handling
code has been removed and replaced by the parameter handling
routines
+ added support for composite parameters (and hence function
results) to tcg.a_load_ref_cgpara() (so it can be used for
handling, e.g., 64 bit parameters on 32 bit platforms)
* the above fixed writing past the end of allocated memory when
handling records returned in registers on x86-64 whose size is
not a multiple of 8 bytes (mantis #16357)
- removed the x86-64 and PPC specific versions of a_load_ref_cgpara(),
as they are now handled correctly by the generic version
* moved the responsibility of allocating tcgpara cpu registers
(using paramanager.allocparaloc()) from the callers of
cg.a_load*_cgpara() to the cg.a_load*_cgpara() methods
themselves (so the register allocation can be done efficiently
when dealing with function results)
* for the above, renamed paramanager.alloc/freeparaloc() to
paramanager.alloc/freecgpara(), and use paramanager.allocparaloc()
to allocate individual pcgparalocations instead
* fixed the register size of SSE2 function result registers for
x86-64 (when used for floating point), which results in removing
a few superfluous "movs? %xmm0,%xmm0" instructions
* fixed compilation of paramanagers of avr, m68k and mips after r13695
and also updated them for these new changes
git-svn-id: trunk@15350 -
tobjectdef.needs_inittable returns false for classes nowadays (and already
since quite some time)
* nevertheless replaced all usages in the compiler of x.needs_inittable with
is_managed_type(x) (in case some other condition is added again in the
future) and removed all remaining accompanying "and not is_class(x)"
checks
git-svn-id: trunk@15320 -
ncgutil it can be used elsewhere too
- removed the code that checks for 64 bit integer types in the float
para loading code, since is_64bit() can never return true for a
floatdef
