* Fixed misplaced parentheses, which were preventing optimization of "unsigned mod power_of_two" into "and" expressions.
* Handling "signed div power_of_two": properly delete the temp node, removes warnings when compiled with "-dEXTDEBUG". This however requires another temp node for storing the result.
* Replaced direct calls to "fpc_sarint64" with inline nodes (in_sar_x_y), allowing target-specific optimizations to take place.

simplified via typeconvnode (corrects resultdef of "qword(1) shl 33",
mantis #22133)
* simplify shl/shr nodes after their resultdef has been set, so the
resultdef used during simplify is set (fixes same expression as above
when it is calculated by an inline function)
git-svn-id: trunk@21394 -
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

from the unit initialisation sections to the variable declaration sections
to prevent the base units from overriding derived classes (based on patch
by Hans-Peter Dietrich, mantis #17516)

that was set during the typecheck pass because typeconversion nodes
may have been optimised away previously and sometimes the resultdef is
important (e.g. for the value of callparanodes) (mantis #17458)

equal to sinttype (Delphi-compatible, fixes#10966)
* changed not(cardinal_constant) into sinttype on 64 bit
platforms for consistency with other similar rules (and with
the above change)
git-svn-id: trunk@10455 -
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)

for qwordbool) + test:
o assigning true to such a variable now sets them to $ff/$ffff/$ffffffff
o these types are now all signed
o converting an integer type to a byte/word/long/qwordbool using an
explicit type cast keeps the integer's original value stored in the
bool, instead of forcing it to ord(true)/ord(false)
(mantis #10233 and #10613, implemented for all architectures, testsuite
tested for ppc32, sparc and x86)
* fixed some places where the rtl depended on longbool(true) having the
value 1
* extended several boolean tests (and adapted some to no longer assume
that byte/word/long/qwordbool(true)=1)
+ support for converting to qwordbool in second_int_to_bool for x86, ppc
and sparc
git-svn-id: trunk@9898 -
* small cleanups of unused variables in firstpass
* node_resources_fpu() created to get an approximation of the
required fpu registers
* for the moment use node_complexity in the CG until the
node_resource_int() is created
git-svn-id: trunk@8655 -
* fixed some (harmless) ptrint warnings
- removed some commented code in agppcmpw
* added one missing field in a typed constant in cp1251
