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.
git-svn-id: trunk@21645 -
they are distinguisable from calculated fields with a FieldNo of -1.
* Added test to check for an exception when the Fields do not correspond to
the underlying data.
* Improved exception message when the Fields do not correspond with the data
git-svn-id: trunk@21641 -
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
