80282d6eff * llvm: only set custom parameter alignments for byval parameters, the rest

c3e2285c45 * when getting an llvm temporary recorddef, recurse into arrays rather than 
treating them as opaque defs. This is required to ensure that the temporary
    recorddef for all x86-64 function results are the same on the caller and
    callee side, as we allocate new arrays when generating them

6e777d8967 * ait_comment,ait_regalloc,ait_tempalloc,ait_varloc instructions produce only comments in the external assembler output. Moved handling of these instructions to TExternalAssembler.WriteComments().

79974a9671 + -XlS<x> option to specify a suffix for externally called LLVM utilities, 
e.g. -XlS-7 to call clang-7 instead of clang)

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

ec0d98156c * use maytrap instead of strict FP exception behaviour in LLVM, so constant

 2020-01-01 19:19:08 +00:00
Jonas Maebe
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)

9b53ed53e3 * the llvm.experimental.constrained.fpext intrinsic doesn't have a rounding 
mode parameter

 2019-12-31 18:05:50 +00:00
Jonas Maebe
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)

git-svn-id: trunk@43821 -
 2019-12-30 15:05:17 +00:00

a6a17efa42 * use LLVM constrained fpext/fptrunc intrinsics when fastmath is not enabled 
for accurate exception behaviour

git-svn-id: trunk@43820 -
 2019-12-30 15:05:13 +00:00

git-svn-id: trunk@43819 -
 2019-12-30 15:05:09 +00:00
Jonas Maebe
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)

git-svn-id: trunk@43818 -
 2019-12-30 15:05:06 +00:00

67dbd0cdb3 * support nf_internal to ignore currency conversion adjustments also on

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)

 2019-12-14 17:15:27 +00:00
Jonas Maebe
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

git-svn-id: trunk@43682 -
 2019-12-14 14:59:05 +00:00
Jonas Maebe
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

git-svn-id: trunk@43681 -
 2019-12-14 14:11:12 +00:00
Jonas Maebe
e775ecdc43 * cleaned up safecall support: use a hidden localvarsym instead of result 
register hacking
   o this also allowed fixing/adding safecall support for LLVM

git-svn-id: trunk@43578 -

     for high level code generator targets

git-svn-id: trunk@43018 -
 2019-09-15 20:43:12 +00:00

ff2d718699 * fixed occasional rounding error with currency constants on the LLVM targets

git-svn-id: trunk@43017 -
 2019-09-15 20:43:09 +00:00
Jonas Maebe
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)

git-svn-id: trunk@42970 -
 2019-09-09 18:33:37 +00:00
Jonas Maebe
dcf4e4cb2c * support taking the address of labels defined in assembler blocks in the

git-svn-id: trunk@42969 -
 2019-09-09 18:33:33 +00:00
Jonas Maebe
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)

git-svn-id: trunk@42477 -
 2019-07-21 11:06:54 +00:00
Jonas Maebe
145f4299b4 * search dynamic string data record in correct symtable in

git-svn-id: trunk@42464 -
 2019-07-20 12:08:59 +00:00
Jonas Maebe
d8903ce6b3 - removed maxcrecordalign parameter/field from recordsymtables, as this value 
cannot be modified in the settings (so we can directly use the one from
    current_settings)

git-svn-id: trunk@42447 -
 2019-07-14 19:24:32 +00:00
Jonas Maebe
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)

fc60ec2ea4 + support for LLVM LTO: compile units with -CLflto -> when compiling a main 
program/library also with -Clflto, all units compiled with that option
    will be linked using their bitcode files and LTO
   o compiling with -CLflto will compile all units twice: once for normal
     (static or smart) linking, and once for LTO. So the result can be
     used both with and without LTO.
