alignment for each memory reference (mantis #12137, and
test/packages/fcl-registry/tregistry1.pp on sparc). This also
enables better code generation for packed records in many cases.
o several changes were made to the compiler to minimise the chances
of accidentally forgetting to set the alignment of memory references
in the future:
- reference_reset*() now has an extra alignment parameter
- location_reset() can now only be used for non LOC_(C)REFERENCE,
use location_reset_ref() for those (split the tloc enum so the
compiler can catch errors using range checking)
git-svn-id: trunk@12719 -
shortstring temps don't get maximum alignment)
* changed some gettemptyed() calls into gettemp() calls (gettemptyped
means that this temp can only be used for temps of that type,
which is necessary for refcounted types but not for floats)
git-svn-id: trunk@12036 -
the syntax is exactly the same as for "external", except for
the keyword. It is currently only active for Darwin targets.
It should also work at least for Linux targets, but only with
the GNU assembler (which is why it is not activated there)
+ test for this functionality
git-svn-id: trunk@12009 -
a) cpu64bitaddr, which means that we are generating a compiler which
will generate code for targets with a 64 bit address space/abi
b) cpu64bitalu, which means that we are generating a compiler which
will generate code for a cpu with support for 64 bit integer
operations (possibly running in a 32 bit address space, depending
on the cpu64bitaddr define)
All cpus which had cpu64bit set now have both the above defines set,
and none of the 32 bit cpus have cpu64bitalu set (and none will
compile with it currently)
+ pint and puint types, similar to aint/aword (not pword because that
that conflicts with pword=^word)
* several changes from aint/aword to pint/pword
* some changes of tcgsize2size[OS_INT] to sizeof(pint)
git-svn-id: trunk@10320 -
* symtables based on TFPHashObjectList and TFPObjectList
* rename torddef.typ to torddef.ordtype
* rename tfloatdef.typ to tfloatdef.floattype
* rename tdef.deftype to tdef.typ
* remove obsolete browser code, browcol is kept so the ide
can still be compiled
git-svn-id: trunk@5192 -
which are used in the loop). The compiler makes now much
more efficient use of registers for register variables (and
different regvars can now also share the same register if
their live range does not overlap)
git-svn-id: trunk@2186 -
getjumplabel and added type para to getlabel for specific types
* moved lineinfo generation from assemble and aggas to dbgstabs
git-svn-id: trunk@1120 -
+ refaddr to treference added
+ refsymbol to treference added
* top_local stuff moved to an extra record to save memory
+ aint introduced
* tppufile.get/putint64/aint implemented
* tregisteralloctor renamed to trgobj
* removed rgobj from a lot of units
* moved location_* and reference_* to cgobj
* first things for mmx register allocation
* ppc get/freeintparaloc now check whether the parameter regs are
properly allocated/deallocated (and get an extra list para)
* ppc a_call_* now internalerrors if pi_do_call is not yet set
* fixed lot of missing pi_do_call's
* procinfo renamed to current_procinfo
* procinfo will now be stored in current_module so it can be
cleaned up properly
* gen_main_procsym changed to create_main_proc and release_main_proc
to also generate a tprocinfo structure
* fixed unit implicit initfinal
+ Add for loop code optimization using notifications
results in 1.5-1.9% speed improvement in nestloop benchmark
Optimization incomplete, compiler does not cycle yet with
notifications enabled.
* Moved pocall_internconst to po_internconst because it is not a
calling type at all and it conflicted when inlining of these small
functions was requested
* asmsymbollist global is removed and moved into a new class
tasmlibrarydata that will hold the info of a .a file which
corresponds with a single module. Added librarydata to tmodule
to keep the library info stored for the module. In the future the
objectfiles will also be stored to the tasmlibrarydata class
* all getlabel/newasmsymbol and friends are moved to the new class
* The whilen and repeatn are now completely unified into whilerepeatn. This
allows the state tracker to change while nodes automatically into
repeat nodes.
* Resulttypepass improvements to the notn. 'not not a' is optimized away and
'not(a>b)' is optimized into 'a<=b'.
* Resulttypepass improvements to the whilerepeatn. 'while not a' is optimized
by removing the notn and later switchting the true and falselabels. The
same is done with 'repeat until not a'.
* foreach gets extra argument for passing local data to the
iterator function
* -CR checks also class typecasts at runtime by changing them
into as
* fixed compiler to cycle with the -CR option
* fixed stabs with elf writer, finally the global variables can
be watched
* removed a lot of routines from cga unit and replaced them by
calls to cgobj
* u32bit-s32bit updates for and,or,xor nodes. When one element is
u32bit then the other is typecasted also to u32bit without giving
a rangecheck warning/error.
* fixed pascal calling method with reversing also the high tree in
the parast, detected by tcalcst3 test
error was found
* generic changeregsize(reg,size) for i386 register resizing
* removed some more routines from cga unit
* fixed returnvalue handling
* fixed default stacksize of linux and go32v2, 8kb was a bit small :-)
* LOC_CONSTANT added for better constant handling
* secondadd splitted in multiple routines
* location_force_reg added for loading a location to a register
of a specified size
* secondassignment parses now first the right and then the left node
(this is compatible with Kylix). This saves a lot of push/pop especially
with string operations
* adapted some routines to use the new cg methods
* register allocation is now handled by a class and is mostly processor
independent (+rgobj.pas and i386/rgcpu.pas)
* temp allocation is now handled by a class (+tgobj.pas, -i386\tgcpu.pas)
* some small improvements and fixes to the optimizer
* some register allocation fixes
* some fpuvaroffset fixes in the unary minus node
* push/popusedregisters is now called rg.save/restoreusedregisters and
(for i386) uses temps instead of push/pop's when using -Op3 (that code is
also better optimizable)
* fixed and optimized register saving/restoring for new/dispose nodes
* LOC_FPU locations now also require their "register" field to be set to
R_ST, not R_ST0 (the latter is used for LOC_CFPUREGISTER locations only)
- list field removed of the tnode class because it's not used currently
and can cause hard-to-find bugs
related things) to processor independent code (in new ncgflw unit)
+ generic cgobj unit which contains lots of code generator helpers with
global "cg" class instance variable
+ cgcpu unit for i386 (implements processor specific routines of the above
unit)
* updated cgbase and cpubase for the new code generator units
* include ncgflw unit in cpunode unit
