o added AArch64 regset parsing support in assembler reader, means that "{"
no longer starts comments there (like in the ARM assembler reader)
o added AArch64 indexed SIMD register support and removed old cg hacks
that worked around its absence

* Reversed sort order of simplifyworklist so nodes with most interferences will get their colors first.
Since degree of nodes in simplifyworklist before sorting is always
less than the number of usable registers this should not trigger spilling
and should lead to a better register allocation in some cases.
After these changes sysutils.o for i386-win32 is 80 bytes less. :)

o they are implemented as a new metadata register class, whereby the
subregister indicates the metadata type (currently always a string)
and the superregister is an index in the metadata array (which
contains the strings). LLVM metadata can only be passed as parameters
to intrinsics in bitcode, so moves of metadata into other registers
triggers internal errors and when moving them into parameters, we
replace the parameter's register with the metadata register (and look
up the corresponding string when writing out the bitcode)

+ AArch64: support for vX.8b/vX.16b register names
+ support for more than 256 registers in the register dat files
- removed totherregisterset
+ AArch64: use vmov to load immediates if possible
+ AArch64: use eor to clear mm registers

references that directly take the address of a symbol, rather than
of its GOT entry
o use these addressing modes to access local symbols
git-svn-id: trunk@29932 -
loaded into a register because of its size
o by default, also allow if the size is the same as OS_ADDR but with a
different sign

temp we allocate, we set the base register to a newly allocated
R_TEMPREGISTER. This allows for uniquely identifying a temp even if its
offset is modified.

* cpugas.pas: GetReferenceString: rewritten, it is easier than trying to fix it. Fixes incorrect writing of non-PIC references containing base, symbol and offset together, and some forms of PIC references. Also supports newly introduced address types.
git-svn-id: trunk@23555 -
cgutils, and define them so they are no larger than what is required by
the current target platform
* added cgutils to the uses clause of several units that use the
tcpuregisterset type
git-svn-id: trunk@21624 -
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
