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

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

* Don't generate rex.w for "CALL|JMP|LCALL|LJMP regmem", they are 64-bit by default.
* LCALL,LJMP flagged as calljump instructions.
* LCALL,LJMP encode only far jumps and don't accept register operands.
* GAS writer: fixed writing rip-relative operands of calljump instructions.
+ test.
git-svn-id: trunk@19413 -
* Insert seh_endprologue directive after the last prologue instruction, not before it
* Omit seh_stackalloc for zero bytes
* (For now) ignore SEH directives in NASM and MASM writers, instead of failing with internal error.
git-svn-id: trunk@19246 -
* For now placed actual processing of unwind info under {$ifdef TEST_WIN64_UNWIND}, because in the current state it doesn't add much value.
git-svn-id: trunk@19200 -
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 -
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)

* Adjust rip-relative offsets using values known from calcsize, instead of reinterpreting the tail of instruction. This is simpler and remains the same regardless of particular codes used in opcode table.
* Reduced maxinfolen to 8.
- 'jmp imm64' and 64-bit versions of 'in' do not exist, removed.
git-svn-id: trunk@17546 -
* mkx86ins.pp: 'regmem' operand type in x86ins.dat must be converted to OT_RM_GPR, not OT_REGMEM. The latter does not restrict register type, allowing to use e.g. xmm registers in place of regular ones.
* Finished 'movd' and 'movq', added some tests for them to tasm2.pp.
git-svn-id: trunk@17515 -
* Optimized the opcode representation of movq and remaining 3DNow instructions
* Disallow immediates not fitting in 32 bits (Mantis #14685) + test
* Disallow push/pop with 32-bit operands in x86_64 + test
git-svn-id: trunk@17490 -
- Removed remaining address-size control codes \300 and \301
- Also removed codes \323, they are no longer necessary once REX is being written on the first literal.
