contains the tcgsize of the entire parameter rather than only of
what is left (-> calculate it from the remaining parameter length)

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 -
TRegNameTable is defined in compiler/rgbase.pas and is an array of
strings, limited to the maximum length of the used register names.
r22792 added a long register name but did not scale the string-size
enough, resulting in the compiler built breaking for arm.
git-svn-id: trunk@22817 -
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
git-svn-id: trunk@22050 -
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 -
left-aligned. Other targets only require this if the total size of the
parameter was > 8 bytes (this last part used to be ensured by
the ppc64-specific version of a_load_ref_cgpara() that was removed in
r20962)
git-svn-id: trunk@21008 -
record has only a single field (and if so, which one) when checking
whether we have to treat the record as if it was actually its first
field that's passed as a parameter (fixes problems with records
with methods, e.g. crash while compiling tests/test/trhlp35)
git-svn-id: trunk@20967 -
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
git-svn-id: branches/jvmbackend@20887 -
support the stabx as understood by gdb, which is a mixture of regular
stabs and stabx (e.g., class/object definitions are completely different
in real stabx). This means that gdb can be used to debug aix programs,
but the native dbx will complain about lots of debug information
constructs
git-svn-id: trunk@20842 -
* renamed some ppc64 stackframe offset constants to the same names as their
32 bit counterparts so they can be used in shared ppc code
