4953ee6271 tcg: Add tcg-runtime.c helpers to all_helpers
For the few targets that actually use these, we'd not report
them symbolicly in the tcg opcode logs.

100b5e0170 tcg: Put target helper data into an array.
One call inside of a loop to tcg_register_helper instead of hundreds
of sequential calls.

Presumably more icache and branch prediction friendly; resulting binary
size mostly unchanged on x86_64, as we're trading 32-bit rip-relative
references in .text for full 64-bit pointers in .rodata.

7850527966 tcg: rework TCG helper flags
The current helper flags, TCG_CALL_CONST and TCG_CALL_PURE might be
confusing and doesn't provide enough granularity for some helpers (FP
helpers for example).

This patch changes them into the following helpers flags:
- TCG_CALL_NO_READ_GLOBALS means that the helper does not read globals,
  either directly or via an exception. They will not be saved to their
  canonical location before calling the helper.
- TCG_CALL_NO_WRITE_GLOBALS means that the helper does not modify any
  globals. They will only be saved to their canonical locations before
  calling helpers, but they won't be reloaded afterwise.
- TCG_CALL_NO_SIDE_EFFECTS means that the call to the function is
  removed if the return value is not used.

It provides convenience flags, to avoid helper definitions longer than
80 characters. It also provides compatibility flags, and updates the
documentation.

c29c1d7edf tcg: rewrite tcg_reg_alloc_mov()
Now that the liveness analysis provides more information, rewrite
tcg_reg_alloc_mov(). This changes the behaviour about propagating
constants and memory accesses. We now take the assumption that once
a value is loaded into a register (from memory or from a constant),
it's better to keep it there than to reload it later. This assumption
is now always almost correct given that we are now sure the
corresponding temp is going to be used later (otherwise it would have
been synchronized and marked as dead already). The assumption is wrong
if one of the op after clobbers some registers including the one
of the holding the temp (this can be avoided by allocating clobbered
registers last, which is what most TCG target do), or in case of lack
of available register.

9c43b68de6 tcg: rework liveness analysis
Rework the liveness analysis by tracking temps that need to go back to
memory in addition to dead temps tracking. This allows to mark output
arguments as "need sync", and to synchronize them back to memory as soon
as they are not written anymore. This way even arguments mapping to
globals can be marked as "dead", avoiding moves to a new register when
input and outputs are aliased.

In addition it means that registers are freed as soon as temps are not
used anymore, instead of waiting for a basic block end or an op with side
effects. This reduces register spilling especially on CPUs with few
registers, and spread the mov over all the TB, increasing the
performances on in-order CPUs.

ec7a869d31 tcg: sync output arguments on liveness request
Synchronize an output argument when requested by the liveness analysis.
This is needed so that the temp can be declared dead later.

For that, add a new op_sync_args table in which each bit tells if the
corresponding output argument needs to be synchronized with the memory.
Pass it to the tcg_reg_alloc_* functions, and honor this bit. We need to
synchronize the argument before marking it as dead, and we have to make
sure all the infos about the temp are correctly filled.

At the same time change some types from unsigned int to uint16_t when
passing op_dead_args.

332864bd95 tcg: mark set_label with TCG_OPF_BB_END flag
set_label is effectively the end of a basic block, as no optimization
can be made accross it. It was treated as such in the liveness analysis
code, but as a special case.

Mark it with TCG_OPF_BB_END flag so that this information can be used
by other parts of the TCG code, and remove the special case in the liveness
analysis code.

4055299ef0 Fix large memory chunks allocation with tcg_malloc.
An attempt to allocate a large memory chunk after a small one resulted in
circular links in list of pools.  It caused the same memory being
allocated twice for different arrays.

Now pools for large memory chunks are kept in separate list and are
freed during pool reset because current allocator can not reuse them.

9d6fca70c7 tcg: Improve tcg_out_label and fix its usage for w64
tcg_out_label is always called with a third argument of pointer type
which was casted to tcg_target_long.

These casts can be avoided by changing the prototype of tcg_out_label.

There was also a cast to long. For most hosts with
sizeof(long) == sizeof(tcg_target_long) == sizeof(void *) this did not
matter, but for w64 it was wrong. This is fixed now.

Remove broken dynamic stack allocation code and replace it with an assert.

functions should be added.

2bece2c883 tcg: Optionally sign-extend 32-bit arguments for 64-bit hosts.
Some hosts (amd64, ia64) have an ABI that ignores the high bits
of the 64-bit register when passing 32-bit arguments.  Others
require the value to be properly sign-extended for the type.
I.e. "int32_t" must be sign-extended and "uint32_t" must be
zero-extended to 64-bits.

To effect this, extend the "sizemask" parameter to tcg_gen_callN
to include the signedness of the type of each parameter.  If the
tcg target requires it, extend each 32-bit argument into a 64-bit
temp and pass that to the function call.

This ABI feature is required by sparc64, ppc64 and s390x.

This patch removes the unused tcg_global_reg2_new_hack() function, which
was added in r4438 to work around a register shortage problem regarding
dyngen.  The only ever user of this function was removed in r4577.

49516bc0d6 Some cleanups after dyngen removal
this patch removes some now unused things after dyngen removal.

1. dyngen-exec.h:  op_param, op _jmp and some associated macros
   are now unused;
2. Makefile.target:  tcg-dyngen is not needed anymore
2. tcg/tcg-op.h, tcg/tcg-opc.h:  gen-op.h is dead
3. tcg.c:
    - INDEX_op_end is now the first op
    - CONFIG_DYNGEN_OP is never defined
4. tcg.h:  dyngen_op not needed anymore
5. exec-all.h:  remove some ASM macros.
