o made all (non-abstract) tdef and tsym constructors virtual
o added c*def/c*sym classref types for every (non-abstract) t*def/t*sym
class
o added cpusym unit for every architecture that derives a tcpu*def/tcpu*sym
class from the base classes, and initialises the c*def/c*sym classes with
them. This is done so that the llvm target will be able to derive from
the tcpu*def/sym classes without umpteen ifdefs, and it also means that
the WPO can devirtualise everything because the c* variables are only
initialised with one class type
o replaced all t*def/t*sym constructor calls with c*def/c*sym constructor
calls

Generate them also for non-PIC mode: absolute code is just 2 instructions shorter, trying to save them is probably not worth the effort.
git-svn-id: trunk@26468 -
* don't bother reusing locations
* don't optimize division into shift if overflow checking is enabled
* if denominator is a constant and fits into 13 bit range, use it directly and save a register.
git-svn-id: trunk@26363 -
+ Enable registers %i0..%i5 and %o7 for use by reg.allocator.
Some notable properties of this implementation are:
o pi_needs_got flag can be safely set during pass 2, so not setting it occasionally in pass 1 does not result in internal error.
o Reg.allocator configuration is independent from PIC. If procedure requires GOT, register %l7 is allocated at the prologue, making it unavailable to RA.
o GOT is stored in fixed %l7 register, but it is trivial to switch over to virtual register.

do_spill_replace routines, will be necessary by llvm register
allocator to determine the tdef corresponding to that register
* replaced uses of taicpu with tai_cpu_abstract_sym in the register
allocator so that it can work both with taicpu and taillvm instructions

cgobj.pas, tcg:
* g_save_registers: add the amount of used address registers to size as well
* g_save_registers: save all used address registers
* g_restore_registers: restore all stored address registers
m68k/cpubase.pas:
* rename saved_standard_address_registers to saved_address_registers
all other platform's cpubase.{inc,pas} (except alpha, ia64 and vis which are not up to date):
* add a saved_address_registers variable with one entry of RS_INVALID
At least a "make fullcycle" did complete.

that the type of the parameters can be determined automatically
o added compilerproc declarations for all helpers called in the compiler
via their assembler name, so we can look up the corresponding procdef
git-svn-id: trunk@23325 -
1) tguidconstnode.pass_1 (location is LOC_CREFERENCE)
2) tonnode.pass_1 (generic secondpass references VMT of exception class)
3) Conversion from unsigned to floating-point involves 'magic constant' as GOT-relative data object.
4) Case jumptable address is loaded relative to GOT.
(1) and (2) also provide more accurate setting of pi_needs_got for all targets.
git-svn-id: trunk@23188 -
* Methods ReportNonDSOReloc and ReportRelocOverflow moved to TElfExeOutput, they are applicable to all target-specific descendants.
git-svn-id: trunk@23094 -
* Moved target-dependent constants into ElfTarget records, eliminates a lot of $ifdef's in ogelf.pas.
+ Added TElfTarget.loadsection hook and pass unknown sections to it.

x86_64 is the most elaborated, has some degree of indirect function (GNU_IFUNC) and TLS support, so it is even able to link with static libc/pthreads code (tw14265) and produce an executable that can launch (but still fails due to invalid DWARF unwind info).
i386 produces working shared libraries if they are compiled with -Cg, without one your mileage may vary. tw14265 does not link yet due to missing COMDAT group support.
git-svn-id: trunk@22775 -
like field reordering (possible problems cracker classes) or using ebp as normal register (broken
stack traces from dump_stack)
+ niln is also valid in a cse domain
* parameters passed by reference shall have a complexity >1
* load nodes from outer scopes shall have a complexity >1
* better cse debugging
+ more node types added to cse
* consider parameters passed by reference in cse
* take care of cse in parameters in simple cases

order to minimise memory losses due to alignment padding. Not yet enabled
by default at any optimization level, but can be (de)activated separately
via -Oo(no)orderfields
o added separate tdef.structalignment method that returns the alignment
of a type when it appears in a record/object/class (factors out
AIX-specific double alignment in structs)
o changed the handling of the offset of a delegate interface
implemented via a field, by taking the field offset on demand
rather than at declaration time (because the ordering optimization
causes the offsets of fields to be unknown until the entire
declaration has been parsed)
git-svn-id: trunk@21947 -
getintparaloc + adapted all call sites of getintparaloc. This
led to a number of additional, related changes:
o corrected the type information for some getintparaloc parameters
o don't allocate some intparalocs in cases they aren't used
o changed "const tvardata" parameter into "constref tvardata" for
fpc_variant_copy_overwrite to make pass-by-reference semantics
explicit
o moved a number of routines that now have to call find_system_type()
from cgobj to hlcgobj so that cgobj doesn't have to start depending
on the symtable unit
o added versions of the cpureg alloc/dealloc methods to hlcgobj that
call through to their cgobj counter parts, so we can call save/restore
the cpu registers before/after calling system helpers from hlcgobj
(not implemented in hlcgobj itself, because all basic register
allocator functionality is still part of cgobj/cgcpu)
git-svn-id: trunk@21696 -
* set tcgpara.def for the function return location (field introduced for and
already used by the JVM code generator, required for future hlcg
functionality)
git-svn-id: trunk@21691 -
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 -
future use by high level code generator targets
o this in turn required that all a_load*_loc* methods are called via
hlcg rather than via cg, since a location can be a subsetref/reg and
and those are no longer handled in tcg
o that then required moving several force_location_* routines into
thlcg because they use a_load_loc*, but did not take tdef size
parameters (which are required by the thlcg a_load_loc* routines)
o the only practical consequence is that from now on, you have to
use hlcg.location_force_mem/reg() (fpureg not yet) and
hlcg.gen_load_loc_cgpara() instead of the removed versions from ncgutil,
and hlcg.a_load*loc*() instead of cg.a_load*loc* if a subsetref/reg
might be involved
git-svn-id: trunk@21287 -
o support for the new codepage-aware ansistrings in the jvm branch
o empty ansistrings are now always represented by a nil pointer rather than
by an empty string, because an empty string also has a code page which
can confuse code (although this will make ansistrings harder to use
in Java code)
o more string helpers code shared between the general and jvm rtl
o support for indexbyte/word in the jvm rtl (warning: first parameter
is an open array rather than an untyped parameter there, so
indexchar(pcharvar^,10,0) will be equivalent to
indexchar[pcharvar^],10,0) there, which is different from what is
intended; changing it to an untyped parameter wouldn't help though)
o default() support is not yet complete
o calling fpcres is currently broken due to limitations in
sysutils.executeprocess() regarding handling unix quoting and
the compiler using the same command lines for scripts and directly
calling external programs
o compiling the Java compiler currently requires adding ALLOW_WARNINGS=1
to the make command line
git-svn-id: branches/jvmbackend@20887 -
of the AVR-specific ifdef'ed variant
o since the only special character we use in mangled names on all platforms
is $, added a new field to tasminfo called "dollarsign" that holds the
character $'s should be replaced with (if it doesn't have to be replaced,
leave it at $)
git-svn-id: trunk@20801 -
since the definition-specific adorning of JVM mangled names is Jasmin-
specific, and such code has no place in symdef
* moved code to adorn JVM mangled names for Jasmin definitions to agjasmin
git-svn-id: branches/jvmbackend@18346 -
o changed type of opsize field of tcgcasenode from tcgsize into tdef,
and fixed compilation of other code generator units after this change
git-svn-id: branches/jvmbackend@18339 -
whether the mangled name is for defining a symbol, or for referencing
it later (e.g. for a call or load of its address). The reason is that
on the JVM both cases are different.
+ jvmdef unit to encode types according to the JVM rules
+ tprocdef.jvmmangledname() to encode a procdef's JVM mangled name
(the common part of defining/referencing it; tprocdef.mangledname
afterwards adorns it as required)
