3d81dd0b00 * ReplaceForbiddenAsmSymbolChars renamed ApplyAsmSymbolRestrictions, because now it also applies the 
label length limit

a8fe46c0f5 + introduced labelmaxlen in tasminfo and added code in ReplaceForbiddenAsmSymbolChars that limits the 
output label to that length

79974a9671 + -XlS<x> option to specify a suffix for externally called LLVM utilities, 
e.g. -XlS-7 to call clang-7 instead of clang)
  * IMPORTANT: changed the -CL llvm code generation options to -Cl, for
    consistency with the new -Xl option (-XL was already taken)

254b85c352 + new pio_inline_forbidden flag to indicate that while parsing the 
implementation the compiler determined the routine must never be
    inlined
   o difference with po_noinline: can also be set in the implementation
   o difference with pio_inline_not_possible: it indicates that e.g.
     LLVM must not inline the routine either

1f5efe2a95 * support for constrained sitofp/uitofp with (the upcoming) LLVM 10.0 
(fixes most of test/units/math/troundm, although there's still an LLVM
     optimizer/code generation bug that breaks some qword -> double
     conversions)

3885ce98ac * fix LLVM code generator after r43808 
o share the high/length code for LLVM rather than duplicating it, since
      LLVM will optimize away the minor inefficiencies
    o removed temp reference in the old code, as it was useless (it doesn't
      prevent spilling to get to an SSA representation since the same
      register is written at least twice in all cases)

b355ba3d39 * record whether a function uses fastmath, and define the function as 
strictfp if it doesn't (so LLVM doesn't perform transformations that can
    change the fp/exception behaviour)

9bd33f7a45 + support for LLVM metadata constant string parameters 
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)

c477816100 - removed LLVM support for clang < 7.0 and Xcode < 10.0: those versions 
contain various bugs and can't even complete "make all", so there is no
    point in keeping them
   o changed default LLVM target version to 7.0

a352a12bb4 * use value_real rather than value_curency when writing currency 
realconstnodes (fixes tcurrency1, tw33439 and tw36179 with LLVM)
   o we need to load the fpu representation of the currency values,
     not the scaled currency value

cdafe680c2 * different definitions for the same Objective-C class (can happen with 
external class declarations) need a type conversion in LLVM (because
    they're represented by different LLVM types)

e7fbebfef5 * fixed field alignment when reusing an anonymous recorddef for LLVM and 
the LLVM layout of an instance does not match the original one
    (e.g. because it contains procdefs of procedures with different
     signatures)

d8903ce6b3 - removed maxcrecordalign parameter/field from recordsymtables, as this value

    current_settings)

3fee990218 * on Mach-O, PECOFF and ELF platforms, write local symbols as hidden/ 
private_extern (or plain global in case of PECOFF, as the effect is
    the same there): visible across object files, but they become local
    when linked into a binary/library. This enables cross-unit inlining
    of functions accessig implementation-only symbols.

1dee4c41dd - removed "cmp 0/1, pasbool1" optimization for llvm because this discards 
the upper 7 bits of the boolean, while other platforms take it into
    account (even though they're technically always required to be 0, and
    the value is undefined if they're not)
