the reference has been used for the last time, as the destination
register could be the base or index register of the reference

In comparison with the original patch, support for a i386 has been added as well as a test program.
Further, a small issue with xbegin has been fixed
git-svn-id: trunk@33375 -
instead of using the optimized instructions for 386+, which assume also a
32-bit address and operand size, so they didn't work even on a 386+ in real
mode
git-svn-id: trunk@33371 -
The added test shows such a bogus warning (sadly the test suite can handle the occurence or absense of certain messages yet :/ )
git-svn-id: trunk@33324 -
supposed to handle in the i8086 internal asm instruction level check, because
these two flags are no longer part of the IF_PLEVEL mask, after r33316
git-svn-id: trunk@33318 -
* WriteTree: implement the ait_realconst case by calling WriteRealConstAsBytes
* WriteTree: remove commented code handling the old constants
git-svn-id: trunk@33288 -
ogmacho.pas:
+ TMachoObjectOutput: new method current_cpu_type to retrieve the cpu_type_t matching the compiler's target platform
* TMachoObjectOutput.writedata: initialize cputarget using current_cpu_type and use cputarget instead of CPU_TYPE_I386 in the call to AllocMachoWriter
* surround the RegisterAssembler call with ifdefs for i386
git-svn-id: trunk@33286 -
systems.pas:
+ add new constant systems_indirect_var_imports to denote all targets that /require/ indirect references for cross-unit variables accesses
git-svn-id: trunk@33284 -
ncgld.pas, tcgloadnode:
+ new method use_indirect_symbol to determine whether using an indirect reference is necessary at all
* generate_threadvar_access & pass_generate_code: pass result of use_indirect_code() to RefAsmSymbol() for using an indirect access if needed
git-svn-id: trunk@33282 -
globtype.pas:
+ tlocalswitch: extend by cs_imported_data
globals.pas:
* default_settings: cs_imported_data is set by default (Delphi compatible)
switches.pas:
* turboSwitchTable: G is used for cs_imported_data
scandir.pas:
+ new directive handler dir_importeddata
* InitScannerDirectives: handle IMPORTEDDATA with dir_importeddata
git-svn-id: trunk@33281 -
x86/cgx86.pas, tcgx86:
+ new method make_direct_ref() which is used to convert an indirect reference into a direct one (uses the boolean field in_make_direct_ref to avoid recursive calls)
* make_simple_ref: call make_direct_ref() before anything else
* a_loadaddr_ref_ref: call make_direct_ref() (the loading could probably be folded into the loadaddr method, but for now that is sufficent)
i386/cgcpu.pas, tcg386:
* a_loadaddr_ref_cgpara: call make_direct_ref(); the same remark as for a_loadaddr_ref_ref() applies here
git-svn-id: trunk@33280 -
Note: It needs to be checked what adjustments will need to be done for JVM and LLVM
Note 2: The indirect symbols will always be generated even if the target won't use them so that assembler code can be consistent among the targets (e.g. i386-win32 needs them while i386-linux does not)
ptconst.pas, read_typed_const:
* generate the indirect symbol in a read only data section
ngenutil.pas, tnodeutils:
* insertbsssym: generate the indirect symbol in a read only data section
git-svn-id: trunk@33279 -
symconst.pas:
+ new constant suffix_indirect which will be used to denote indirect symbols
aasmbase.pas:
* TAsmsymbind: extend by AB_INDIRECT (which is used to define an indirect symbol) and AB_EXTERNAL_INDIRECT (which is used when an unknown indirect symbol is requested)
* asmsymbindname: adjust for TAsmsymbind changes
+ new constant asmsymbindindirect which is a set of both indirect asm symbol binds
aasmdata.pas, TAsmData:
* DefineAsmSymbolByClass: adjust to correctly declare an indirect symbol (with suffix_indirect) if one of the indirect asm symbol binds is used
* RefAsmSymbol: extend by a boolean parameter which is used to request an indirect symbol (usually AB_EXTERNAL_INDIRECT instead of AB_EXTERNAL)
git-svn-id: trunk@33278 -
* a_load_ref_cgpara: call make_simple_ref() before calling the base a_load_ref_cgpara()
x86/cgx86.pas, tcgx86:
* a_loadfpu_ref_reg, a_loadfpu_reg_ref, g_concatcopy: call make_simple_ref() on the passed references
git-svn-id: trunk@33277 -
psub.pas, tcgprocinfo.parse_body:
* ensure that parse_generic and current_genericdef are set correctly when parsing a generic routine
pgenutil.pas, generate_specialization_phase2:
* when we're specializing inside a generic we don't want to have the routine definitions, so let the compiler assume that the routine is no longer a forward definition
+ added test
git-svn-id: trunk@33275 -
i386/popt386.pas, PeepHoleOptPass1:
* disable the call to RegLoadedWithNewValue() as that method isn't implemented for any of the x86 optimizers (but add a ToDo so that it isn't forgotten)
