+ Store size of relocation and explicit addend in TObjRelocation (reusing 'orgsize' field for the latter). This removes need for reading addends back from section data, addends are stored in full 64 bits and therefore not truncated.
+ Relocation style is now controlled by relocs_use_addend variable instead of $ifdef's.
- Removed (never working) checks forbidding relocations of readonly sections. At the linking stage readonly sections *can* have relocations, executable stage is different matter to be handled elsewhere.
- removed ugly hack with mapping 32-bit absolute relocations to RELOC_RVA.
+ support 64-bit relative relocations.
* actualized list of x86_64 relocations.

This now generates:
mvn r0, r0, lsl #24/#16
mov r0, r0, lsr/asr #24/#16
The lsr/asr might be folded into a following instruction, making the
whole operation 1 cycle instead of 2-3 with the previous solution.
git-svn-id: trunk@21658 -
* pscanner.pas, tscannerfile.replaytoken: remove the checks for "sources_avail" and always update the read file/line information
* fppu.pas, tppumodule.readsourcefiles: always load at least the filenames which were used when compiling the unit from the ppu file, so that file/line information will be correctly shown, but don't touch the "sources_avail" flag of the tppumodule
git-svn-id: trunk@21657 -
* pgenutil.pas: factor out the reading of generic specialization parameters (parse_generic_specialization_types) and the generation of a generic type name (generate_generic_name)
* pdecsub.pas, parse_proc_head:
* also allow an interface alias declaration if an identifier is followed by a "<" (which starts a specialization)
+ add a procedure "consume_generic_interface" which parses such a specialization (by using "parse_generic_specialization_types") - this is needed, because "consume_generic_type_parameter" can (and should not!) handle "ISomeIntf<Integer, T>" or (somewhen in the future) "ISomeIntf<TSomeOtherGeneric<T>>" - and finds the correct symbol for the interface (by utilizing the "generate_generic_name" function)
* generate the correct mapping entry (for the generic it's only needed for checking (if any), but for a specialization it's essential that we reference the correct specialization)
+ add tests which were included with the issue and also two additional ones
Note: In non-Delphi modes an interface alias can be done like in Delphi mode; "specialization" is not necessary and furthermore not even allowed!
git-svn-id: trunk@21656 -
* pscanner.pas: change SizeInt to ASizeInt for tokenreadsizeint and tokenwritesizeint and change necessary other locations for record- and replaytokenbuffers
+ Added a test in the hope that some test-platforms do cross platform (e.g. win32 => win64) compilation.

OP_ADD, OP_SUB, OP_ORR will be split into two intructions if possible when a load/const
construction is required.
OP_AND is a bit different, because we can't just split it up, but we try
to find a two instruction BIC-equivalent to it.
Till now code like
a:= a and $FFFF;
produced code like
mov r0, $FF00
orr r0, r0, $FF
and r1, r1, r0
With this addition we produce code like:
bic r0, r0, $FF00
bic r0, r0, $FF
Saving us at least a cycle and in some cases also a load from the
constant-pool.
This uses the new split_into_shifter_const function.
git-svn-id: trunk@21647 -
* use split_into_shifter_const to reduce the MOV/ORR combination to a
single check and allow a broader rang of combinations.
* Introduce MVN/BIC combination to load values which have more 1 than 0
bits set (like small negative values)
git-svn-id: trunk@21646 -
This functions tries to split up a 32-bit value into two shifter
constants. This approach finds a broader range for two shifter constant
combinations.

cgutils, and define them so they are no larger than what is required by
the current target platform
* added cgutils to the uses clause of several units that use the
tcpuregisterset type
git-svn-id: trunk@21624 -
RS_INVALID superregister (instead of sometimes RS_NO and sometimes
RS_INVALID)
* check for RS_INVALID in tcg.g_save_registers() and ignore such entries
git-svn-id: trunk@21622 -
* pparautl.pas, insert_funcret_para:
assume that the result in a generic function/method can not be passed in a param
* pparautl.pas, insert_funcret_local:
don't call ret_in_param, but create the symbol as we need a valid funcretsym
* pstatmnt.pas, assembler_block:
don't modify the framepointer for a generic method/function
* rautils.pas, TOperand.SetupResult:
don't assume that we can't use the result for a generic function/method
git-svn-id: trunk@21608 -
+ pgenutil.pas:
add a procedure which adds a type symbol to a non-Delphi-mode generic class or record which has the same name as the unit global dummy symbol for that generic. I don't know why I had that idea earlier as this will simplify some of the conditions in the parser again (I haven't changed these yet, but I hope to do that at least when I start working on generic functions).
* pgenutil.pas, generate_specialization:
correctly handle "specialize TSomeGeneric<T>" as method parameter in a generic with the newly added rename symbol
* pdecobj.pas, object_dec & ptype.pas, record_dec:
call the procedure to add the rename symbol (the procedure checks whether the mode is correct)
* ppu.pas:
increase PPU version so that we don't use non-Delphi mode units with generics, but without the rename symbol
+ added tests:
the one in webtbs are for classes/objects and those in test are for records

21558:
use inherited first_int_to_real to avoid mixing doubles and singles
it fixes the failure of test/cg/taddcurr.pp
21559:
set default round mode to round nearest instead of round to zero
it fix test/cg/taddcurr.pp
21560:
enable softfpu, default first_int_to_real depends on int64_to_float64/32 etc.
It is needed by the patch of r21558

Make macro MIPS/CPUMIPS/MIPS32 common for big endian and little endian mips processors
use MIPSEL* for little endian systems
use MIPSEB* for big endian systems
git-svn-id: trunk@21599 -
use NR_R1 instead of NR_R3 for big stack adjustment temp register(R1 is $at, more suitable)
use A_JR for register operands, although the assembler can translate J to JR when necessary, it is more clear
git-svn-id: trunk@21596 -
+ Add CYCLELEVEL variable, whose value can be from 1 to 3
to be able to modify used options at a specific level,
using OPTLEVELX, LOCALOPTLEVELX and RTLOPTLEVELX
with X being the current value of CYCLELEVEL.
extcycle: Append to value of OPT variable instead of overwriting it.
fullcycle: Remove i386 target for x86_64 source cpu
as this does not work for windows-64bit.
