6071263469 * use ` instead of ^ as replacement character in LLVM asmnodes, as ^ can 
appear in ARM inline assembly

e829596750 * type left-over parts of parameters as arrays of "stack slot alignment" if 
they're an exact multiple of the ialignment size on LLVM. This prevents
    both overalignment (e.g. remainder of 8 individual bytes on ARM
    would be aligned to 8 bytes instead of 4 if typed as int64) and
    underalignment (e.g. 32 bytes remainder of a record that needs to be
    aligned to 8 bytes would be aligned to 1 or 4 bytes if types as
    array of resp. bytes or longints)

bc77aad3d9 * give an error when trying to call through to a C varargs routine with a 
high level code generator

07bd4ba517 * let all the case code generation work with tconstexprint instead of aint, 
so it also works for 32 bit targets and a high level code generator
    (where aint is still 32 bit, but 64 bit operations are not decomposed)

c1e93bd2c2 + compiler/symdef.pas: Add missing call to tderef.reset methods in all tdef constructors. 
+ compiler/sysmsym.pas: Do the same for for all tsym constructors.
  + compiler/symtype.pas: Generate internalerror in  tcompilerppufile.putderef
    if a deref field has index -1, as this means that buildderef was not called
    while it should have been called.
  + compiler/symtable.pas: Fix bug report itself by adding an extra local variable
    CHANGED to add extra cycles in tstoredsymtable.buildderef_referenced method.

New tests for this bug report: tests/webtbs/tw35139.pp and  tests/webtbs/tw35139a.pp

8b9e90dc7a * keep track of whether a routine has a C-style variadic parameter in the 
procoptions even when it's through an array-of-const parameter
  * always call create_varargs_paraloc_info() instead of create_paraloc_info()
    in the former case, even when no varargs parameters are specified (because
    on some platforms even some non-variadic parameters need to be passed
    differently, such as on ARM with gnueabihf)

382d5060a0 * aarch64: According to ARM64 ABI, function's arguments and the result are not required to be sign/zero extended to a full register size. Obey this rule for all targets except iOS where sign/zero extension is required.

3a43ffd57b * arm: Include pi_needs_got to current_procinfo.flags when the GOT register is accessed. It forces proper initialization of the GOT register at the beginning of a procedure. This fixes storing of a double constant to a field in a packed record and other rare copy operations when PIC is enabled.
