08791712d7 * also specify the byval alignment at the callee side

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)

f9668f8c03 * let de LLVM parameter manager merge multiple paralocs used to represent a 
single ordinal, as such splitting is handled by LLVM itself (and handling
    such split locations is currently not supported by our LLVM code generator)

a72a12eef6 * don't emit 0-sized parameters for LLVM: clang doesn't either, and some 
LLVM backends (like the AArch64 one) trigger internal errors when
    encountering them

acf02ab64b * when creating wrappers, add a prefix to parameter names to prevent them 
hiding the method name of the wrapped routine
   o also add a few more '&' prefixes to the generated wrapper code to
     prevent issues when keywords are used as identifiers

f3d831b480 * fixed result cgsize of LLVM's second_nothing type conversion node (new 
size instead of original size, which can be different in case of going
    from void to something else)

eb769e3859 * force pointer-based self parameters of inlined routines in temps for LLVM

dd29088430 * simplify all type conversions for formal constants even for LLVM and JVM 
(since these happen at compile time and don't result in generated code,
     they never need extra type conversions in the code)

c55ffa8cc7 * fixed <> comparisons with NaNs (use LLVM "unordered" comparison: succeed 
if either operand is a NaN)

3b4011760a * cleaned up blockaddress instruction (add type rather than hardcoding it 
in the assembler writer)
  * fixed taking the address of a label in a typed const for llvm (fixes
    tbs/tb0468a)

2330164ee2 + internal sqrt support for LLVM (faster on all platforms, necessary on 
platforms that don't have RTL support for it, as the the generic
    fpc_sqrt_real just calls runerror)

93e39fb0cd * only coerce the type of the leftover bytes of a record if the location 
size doesn't match the number of remaining bytes
   o prevents a second "single" field of a record getting interpreted as a
     "cardinal"

97bc58d248 * fixed bug that caused the "sret" argument attribute to never be used (and 
a guaranteed internalerror on AArch64/llvm)

51502874af * emit temp lifetime information for llvm 
o also allow freeing temps in the middle of a routine for llvm (we won't
     reuse them, but it results in better lifetime information)

50ab607676 + customint torddef type to create arbitraty bit-width integers 
o use this to handle non-power-of-two-sized parameters for llvm
   o no general support in the parser/code generator, so don't expose

0b246f3dbd * converted Boolean8 to an internal type, and mapped Boolean to the 
new internal pasbool1(type) (part of mantis #34411)
   o apply the _Bool x86-64 parameter passing rules only to pasbool1

3da67019e5 * fixed llvm compiler compilation after r38814 (crashes in "make cycle", but 
that was already the case before)

Jonas Maebe
4686f61002 * keep track of the temp position separately from the offset in references, 
so that they can still be freed after the reference has been changed
    (e.g. in case of array indexing or record field accesses) (mantis #33628)

e4dbd24a49 + inline trunc() support for the LLVM backend when using -Oofastmath (because 
the behaviour of LLVM's fptosi instruction is undefined in case of
    overflow)

04ac44cd37 - removed dependency of hlcgllvm on llvmpara, so that cpupara no longer 
indirectly depends on llvmpara and hence is initialised after instead
    of before it (since llvmpara should override cpupara in its init code)

28e5636daa + support for LLVM nil assembler symbols in instructions (write as "null") 
+ support for LLVM nil tai operands (will be used for terminating a daisy
    chain of catch/filter clauses of landingpads): don't try to write it

7503c2bd3e * changed llvmgettemprecorddef() to take an open array instead of a tfplist 
as list of defs to be stored in the record, so we don't need to create and
    free a class instance every time we call this routine

b936d8f012 * don't internalerror when performing an LLVM tc_equal conversion from one 
TP-style object to another and the sizes differ, at least if they are
    related
  * restructured and commented the LLVM type conversion checks

f55d962e40 * use system.round() instead of LLVM's fptosui operation for converting a 
floating point type to currency, as fptosui is defined as always rounding
    to zero while on other platforms we use the FPU's current rounding mode
    (fixes webtbs/tw21449 for LLVM, and also webtbs/tw24197 because LLVM's
     code generated for fptosui temporarily changes the FPU control word so
     it rounds to zero and also to disable FPU exceptions)
