+ added support for constructing target triplets
* pass "-target triplet" when using an LLVM assembler
o removed no longer needed $DARWINVERSION and $ARCH parameters
* consistently use as_clang_gas when clang is used to assembler GAS-style
assembly, and rename as_llcm_clang to as_clang_llvm (for consistency)
* support pipe assembling when using clang on *nix in all cases

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)

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
git-svn-id: trunk@44065 -
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)

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 -
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.

even when it's the same as the stack alignment (it can also refer to the
alignment of the data pointed to by pointer parameters)
git-svn-id: branches/debug_eh@41729 -
pure assembler routines and for generating the CFI tables, and does nothing
for LLVM-handled routines (LLVM takes care of the CFI there)
git-svn-id: branches/debug_eh@41580 -
* adapted string used for macOS/iOS version in triple in llvm IR files to
what clang expects (always a single digit patch version)
git-svn-id: branches/debug_eh@40431 -
store tai in them
+ support for direct symbol parameters to llvm routines (without first
loading them into register)
o needed to pass such symbols to llvm intrinsics
git-svn-id: branches/debug_eh@40414 -
exceptions for LLVM (except on Windows targets, since they (will) use
their own kind of exception handling)
o ensure we generate an external function symbol definition for such
personality functions on LLVM
git-svn-id: branches/debug_eh@40402 -
+ 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
