Although basic things work (no regressions in test suite, also with TEST_OPT=-O2), there are some secondary issues/TODOs:
- Exception frame around PASCALMAIN is not properly removed in DLLs
- No stack traces yet
- Stack overallocated in finalizer procedures, their entry/exit code needs cleanup
- Signals unit is probably completely broken.

default -O1/2/3 optimization levels and supported optimization switches

git-svn-id: branches/hlcgllvm@26055 -
o no support yet for many ait_* types, although eventually most of them
shouldn't be generated at all for the llvm target
o no support yet for calling "opt" (which optimises llvm bitcode) before
calling llc (which translates llvm bitcode into native code) -- compile
with -s and manually call "opt" with -std-compile-opts, -O1, -O2 or -O3

Therefor the cpu type (-Cp...) "coldfire" was split up into "isaa", "isaa+", "isab" and "isac". The Linux RTL can currently compiled for "68020", "isab" and "isac". For the other three Bcc.L must be handled differently (only Bcc.B/W supported) and for "68000" also EXT.L needs to be handled differently.
fpcdefs.inc:
+ define CPUCAPABILITIES if capabilities can be set for a certain CPU type (currently ARM, AVR and M68k)
options.pas:
* check for CPUCAPABILITIES instead of specific CPUs
assemble.pas:
- the handling of the CPU type is already done in m68k/ag68kgas.pas, Tm68kGNUAssembler.MakeCmdLine (and thereby already using the gascputypestr array!)
m68k/cpuinfo.pas:
- tcputype: remove "cpu_coldfire"
+ tcputype: add "cpu_isa_a", "cpu_isa_a_p", "cpu_isa_b" and "cpu_isa_c"
+ add "cpu_coldfire" constant which contains all Coldfire specific cpu types
* adjust "cputypestr" and "gascputypestr"
+ add tcpuflags and cpu_capabilities (DBRA restriction was checked with CPUCOLDFIRE, CAS/TAS will be needed for atomic operations and BRAL restriction was discovered during testing of new cpu types)
m68k/cgcpu.pas:
* adjust checks for "cpu_coldfire"
m68k/n68kadd.pas:
* don't use a BRA.L if it is not supported, but (at least for now) a BRA.W
aggas.pas:
* adjusted check for Coldfire
git-svn-id: trunk@25457 -
* Changed direct references to linker classes in TSystemInfo records to enumerated ids.
* RegisterExtennalLinker and RegisterInternalLinker procedures replaced by single RegisterLinker procedure and moved to link.pas.
- TAbstractLinker is no longer necessary, removed.
This change allows to register linker once per id, rather than once per target, and also allows TSystemInfo records to be read-only.

- i386/cgcpu.pas: removed segment check, rejecting references with segment here is too early. These references are passed to tcgx86.a_loadaddr_ref_reg, which can generate required code for them (or reject if they are not allowed for the target).
- ncgld.pas: removed "not tf_section_threadvars in target_info" condition, it is inverse to one on the following line, making non-generic branch impossible to execute.
+ Define FPC_SECTION_THREADVARS macro if corresponding flag is set for the target.

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

o if neither the parameter nor the environment variable is used, use preset
default values
o pass on this version setting on to the Darwin linker
o use this setting to determine which version of the startup code (crt1.o

When arguments are temps, they are supposed to be released by tcgcallnode.release_para_temps. However, taking address with taddrnode effectively changes original location of temp to some LOC_REGISTER, tcgcallnode.release_para_temps no longer sees the original location and therefore does not free such temps.

(= Android 4.0) java headers: java.*, javax.*, org.*, junit.*, android.*).
The RTL can also be used to target earlier versions of the Android
platform, but you manually have to take care of not using APIs that
weren't available yet. Adding separate units for separate platform
versions would only partly solve the problem, because some of the
classes used inside the system unit have also changed across
versions.
Use -Tandroid while compiling to select the Android OS as target
platform.

var-parameters on the JVM target for changes to the value passed

is a local variable because then reading it before the call may result
in a bytecode verification error (since the variable may not yet be
initialized)
