* force the left operand into a register if both the left and
right are constants (can happen because not all set add-nodes
are handled in taddnode.simplify) because the code below
expects at least one register operand. Fixes the compilation of a.o.
taddset2 with -O3 on ppc (constant propagagation -> 2 constant
operands)

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

symbols on darwin/ppc and darwin/i386, and also for common symbols on
darwin/ppc, as they're not required for other kinds of symbols on those
platforms (gcc doesn't use them either with -O1 and higher; it does use
them always for darwin/ppc64 except for local symbols, and hence so do we)
git-svn-id: trunk@22271 -
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 -
method is only used anymore internally in cgobj.tcg and its descendants
* made tcg.g_indirect_sym_load() protected to ensure it stays that way
git-svn-id: trunk@21392 -
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

(= equivalent of gas .quad), because .llong forces the alignment to
8 bytes and this causes problems with some typed constant records (such
as RTTI)

be generated for a single object file on AIX, automatically switch to
an indirection scheme that uses much less TOC entries, but is slower to
access global variables
* manually merged infrastructure for target-specific code generation
switches from JVM branch (-CTxxx switches)
* -CTsmalltoc switch for AIX that forces the indirection scheme for TOC
entries from the start in case the automatic one does not conserve
a sufficient amount (or in case you bump up against the global TOC
entries limit during linking)
git-svn-id: trunk@20963 -
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

to low addresses in case the target cpu/OS does not support this (enabled
for reads on AIX/PPC because on AIX the first 16KB are readable)
git-svn-id: trunk@20832 -
o .short/.long/.llong are automatically aligned to 2/4/8 byte multiples
by the AIX assembler (and for compatibility reasons, also by the
GNU assembler when targeting AIX) -> change to .vbyte statements
o .ascii does not allow non-ASCII characters in the AIX assembler
-> change to .byte sequences like gcc on AIX
git-svn-id: trunk@20803 -
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 -
* renamed some ppc64 stackframe offset constants to the same names as their
32 bit counterparts so they can be used in shared ppc code
git-svn-id: trunk@20794 -
* fixed code dealing with symbol+offsets on 64 bit platforms in
case of offsets > 32 bit (and to use smallint() typecasts
instead of lo(), since the return value of lo() depends on
the type passed in)
git-svn-id: trunk@20793 -
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

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)
git-svn-id: branches/jvmbackend@18288 -
* $CPU/cgcpu.pas: disable the generation of VMT loading code
* dbgstabs.pas, dbgdwarf.pas: treat virtual methods of helpers as normal methods
* ncgcal.pas: don't register virtual helper methods for WPO
* ncgrtti.pas: write virtual helper methods as normal methods to RTTI
* nobj.pas: correctly handle final and override cases in helpers
* pdecvar.pas: property getters
* rautils.pas: no VMT offset in records
git-svn-id: branches/svenbarth/classhelpers@17150 -
- sort of reverted r14134, which is no longer required after the above
change (new_section() inserts the alignment itself)
* made the tai_section.create() constructor private so it cannot be
called directly anymore
