fde944bf5d + Declare AT_TLS and AT_GNU_IFUNC symbol types, these are needed to handle object files created by gcc in ELF internal linker.
* TExeOutput.FixupSymbols:
  + Collect AT_GNU_IFUNC symbols in IndirectObjSymbols list for further processing by ELF back-end.
  * Do not overwrite bind and size while fixing AB_COMMON symbols, this removes need in storing symbol size in every relocation and dedicated handling of oso_common section.
  * Remove symbols with objsection<>nil from lists, so calling FixupSymbols several times skips already processed symbols.

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

ac43eb9b70 + generic implementation of ReplaceForbiddenAsmSymbolChars() instead
of the AVR-specific ifdef'ed variant
   o since the only special character we use in mangled names on all platforms
     is $, added a new field to tasminfo called "dollarsign" that holds the
     character $'s should be replaced with (if it doesn't have to be replaced,
     leave it at $)

0c675a4039 * the objc1 unit has been renamed to objc
* the objc unit links against the Foundation instead of against the Cocoa
    framework, and inludes an interface to either the fragile or non-fragile
    obj-c run time depending on the target platform
  + support for the non-fragile Objective-C runtime/ABI, as used on Mac OS X
    for ARM (iPhone) 64 bit (PowerPC/64, x86_64) -- all these targets now
    are now also supported for the objectivec1 modeswitch
  + support for private_extern symbol bindings, required for the above
  * mark objcclasses that are declared in the implementation section of a
    unit as "hidden" (not sure what the effect is, since the Objective-C
    runtime does not seem to do anything with this flag)
  * enabled all obj-c tests for the newly supported platforms

ec8fee45fe * do not access local data via the GOT on x86_64, because
a) it's unnecessary
   b) it's slower than "direct" RIP-relative accessing
   c) it's not supported on darwin/x86_64 in certain cases
  * never use absolute addressing on darwin/x86_64 (like on win64)
  * when not generating PIC, make sure that a_loadaddr_ref_reg on x86_64
    also uses RIP-relative addressing for darwin/x86_64 and win64

6165536b5e + added {$modeswitch objectivec1}/-Mobjectivec1 mode switch to enable
the use of Objective-C 1.0 constructs. Because it is a mode switch, it
    can be used cumulatively with every syntax mode. Note that a {$mode xxx}
    statement resets all mode switches as well, so you cannot use the
    -Mobjectivec1 variant if you have such a statement in a unit. This
    modeswitch is currently only enabled for Darwin/PowerPC and Darwin/i386,
    as the backend support is not yet implemented for other platforms.
  + implemented selector() statement that can be used to create an Objective-C
    selector for the message with the specified *constant* name (in the future,
    it will also work for Objective-C method identifiers)
  + added SEL type to the system unit (the selector() statement returns it)
  + added all Objective-C segments to the assembler writers
  + (currently mostly dummy) objc1 unit that is automatically included if the
    {$modeswitch objectivec1} statement is used
  + some tests for the selector() statement

a23630260b + "weakexternal" support for imported procedures and variables.
the syntax is exactly the same as for "external", except for
    the keyword. It is currently only active for Darwin targets.
    It should also work at least for Linux targets, but only with
    the GNU assembler (which is why it is not activated there)
  + test for this functionality

70c2414daa * split off sec_rodata_norel from sec_rodata, and only put constant data
without relocations in sec_rodata_norel. It should be possible to make
    this new section read-only on all platforms, although currently it
    is only done for darwin, and for non-pic code written using the
    -Aas assembler writer.

    Most platforms also have a special section for "constant but with
    relocations" data, but such a section is currently only used for
    Darwin (others still use plain .data sections for that, like they
    did before)
