24c7b7f433 * If alignment requirement of data is bigger than alignment of the section being written to, increase section alignment to match. This mostly affects cases of non-smart linking, where wrong initial alignment used to cause hard to catch misalignment issues. It also largely obsoletes the need to supply the initial section alignment (hidden tai_section constructor,etc).
* Likewise, when merging object sections into exe sections, set alignment of exe section to maximum value.

dc03282cb7 + Support assembling expressions ".long L2-L1" where label L1 belongs to the current objsection and L2 comes from any objsection. This is done using relative relocations and is compatible with GNU AS.
* Also fixed ogcoff.pas to handle these relative relocations correctly.

14cfe770a4 * replaced most (if not all) remaining fields/parameters in the compiler
that deal with paths/filenames with TPathStr (= ansistring) to prevent
    cutting off long paths (no change in speed when compiling the compiler,
    1% extra memory usage)

02413c8a57 * moved maybequoted() from cutils to cfileutl and let its behaviour vary
based on the actual target platform rather than always on the host
    platform
  * on Unix, use single rather than double quotes for quoting, so it also
    properly handles $, ! and `, which keep their special meaning when
    appearing in scripts inside double quotes
  * since sysutils.executeprocess() can only deal with double-quoted
    strings in parameters, re-quote parameters on Unix when they turn
    out not to be for scripts but for direct execution (which is most
    of the time, but unfortunately doing the reverse is not possible
    because parameters used in scripts sometimes contain script-specific
    code that must not be quoted, such as `cat link.res`)
   -> always use cfileutl.RequotedExecuteProcess() rather than
    sysutils.ExecuteProcess() in the compiler (added a bunch of dummy
    ExecuteProcess string constants to common units to prevent accidental
    usage)

aee5380ae0 * merged trunk up to r20882
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

    long double, and to "double" elsewhere)

d1538ab023 o added ARM VPFv2/VFPv3 support:
+ RTL support:
      o VFP exceptions are disabled by default on Darwin,
        because they cause kernel panics on iPhoneOS 2.2.1 at least
      o all denormals are truncated to 0 on Darwin, because disabling
        that also causes kernel panics on iPhoneOS 2.2.1 (probably
        because otherwise denormals can also cause exceptions)
    * set softfloat rounding mode correctly for non-wince/darwin/vfp
      targets
    + compiler support: only half the number of single precision
      registers is available due to limitations of the register
      allocator
    + added a number of comments about why the stackframe on ARM is
      set up the way it is by the compiler
    + added regtype and subregtype info to regsets, because they're
      also used for VFP registers (+ support in assembler reader)
    + various generic support routines for dealing with floating point
      values located in integer registers that have to be transferred to
      mm registers (needed for VFP)
    * renamed use_sse() to use_vectorfpu() and also use it for
      ARM/vfp support
    o only superficially tested for Linux (compiler compiled with -Cpvfpv6
      -Cfvfpv2 works on a Cortex-A8, no testsuite run performed -- at least
      the fpu exception handler still needs to be implemented), Darwin has
      been tested more thoroughly
  + added ARMv6 cpu type and made it default for Darwin/ARM
  + ARMv6+ implementations of atomic operations using ldrex/strex
  * don't use r9 on Darwin/ARM, as it's reserved under certain
    circumstances (don't know yet which ones)
  * changed C-test object files for ARM/Darwin to ARMv6 versions
  * check in assembler reader that regsets are not empty, because
    instructions with a regset operand have undefined behaviour in that
    case
  * fixed resultdef of tarmtypeconvnode.first_int_to_real in case of
    int64->single type conversion
  * fixed constant pool locations in case 64 bit constants are generated,
    and/or when vfp instructions with limited reach are present

  WARNING: when using VFP on an ARMv6 or later cpu, you *must* compile all
    code with -Cparmv6 (or higher), or you will get crashes. The reason is
    that storing/restoring multiple VFP registers must happen using
    different instructions on pre/post-ARMv6.

f36e5411af * split cpu64bit compiler define into
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)

59365a6db9 - garbage was being output sometimes instead of source lines when compiling with -al. This is because lastfileinfo and lastinfile were never initialized for MASM writer. This is true for TPPCMPWAssembler, too.
- long lines were not wrapped.
- constants of type ait_comp_64bit output incorrectly.
- at end of file, current segment was not closed.
