* UnicodeToUtf8: calculate UCS4 value without three (!) temp string variables. Also removed separate word-sized variable and unsigned subtractions.
git-svn-id: trunk@20268 -
* Assume code page of empty addend matching the destination (StringCodePage returns value of DefaultSystemCodePage for empty strings, causing unnecessary conversions if another addend has a non-default code page).
* Moved part with temp Unicodestring variables into separate procedure in order to avoid an implicit try..finally block in primary control flow.
* Renamed Size and Location varialbles into S1Len and S2Len.
git-svn-id: trunk@20230 -
* Handle codepage the same way in all control flow branches (was different for the cases of allocating a new string and reallocating an existing one)
* Don't assign intermediate values directly to var-parameter, use local pointer instead.
* Setting string pointer to nil after fpc_ansistr_decr_ref is no longer necessary.
- fpc_ansistr_copy: removed repeating index check and unecessary typecasts.
git-svn-id: trunk@20209 -
* align(): tweaked priority of calculation, yields better constant folding when these functions are inlined (alignment argument is a constant in most cases)
git-svn-id: trunk@20197 -
o Makes behavior predictable in cases when source and destination strings happen to overlap.
o Removes need in CPU-specific implementations, at least for CPUs having optimized IndexByte and Move implementations.
git-svn-id: trunk@20196 -
* 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%.

It appears that a function which is present in interface part and aliased to another function using "external name 'foo'" directive cannot be placed immediately before the function to which it is aliased. The body of first function consists of a single jump which fails to be correctly relocated.
git-svn-id: trunk@20053 -
* 'dimcount' parameter is now of type sizeint everywhere (was dword in fpc_dynarray_setlength and longint generated by compiler).
Since multi-dimensional dynarrays are not used in compiler code, this change does not break cycling.

When arguments are temps, they are supposed to be released by tcgcallnode.release_para_temps. However, taking address with taddrnode effectively changes original location of temp to some LOC_REGISTER, tcgcallnode.release_para_temps no longer sees the original location and therefore does not free such temps.
git-svn-id: trunk@19959 -
- i386-specific fpc_shortstr_append_shortstr removed too, because a) it was anyway disabled with STR_CONCAT_PROCS, b) the generic implementation is smaller and probably faster due to optimized Move().
git-svn-id: trunk@19867 -
* In win32/sysinitXX units, rename EntryInforation
to SysInitEntryInformation.
include new win/systlsdir.inc file from
win/syswin.inc for win64 target
and from win32/sysinit.inc for win32 target.
Set fields of both SysInitEntryInformation and EntryInformation
by converting them into typed constants.
git-svn-id: trunk@19779 -
* fpc_help_constructor: call platform-optimized version of FillChar directly instead of going through generic overloaded version.
* don't compile software multiplication routines if not necessary (the interface part already has similar $ifdef around)
* fpc_shortstr_append_shortstr: use sizeint instead of integer (the latter is 16-bit, produces less efficient code on most platforms)
