Add a little shell script to auto-generate runtime.sigtable from the
known signal names.
Force the main package to always import the runtime package. Otherwise
some runtime package global variables may never be initialized.
Set the syscallsp and syscallpc fields of g when entering a syscall, so
that the runtime package knows when a g is executing a syscall.
Fix runtime.funcPC to avoid dead store elimination of the interface
value when the function is inlined.

When combine splits a three-insn combination into two instructions it
can reuse i2dest for the temporary result of the first new instruction.
However all information it has in reg_stat about that register will be
stale. This results in the simplify_gen_binary calls in change_zero_ext
using out-of-date information, which makes it think one of the ANDs
generated there always results in 0, and it doesn't get better from there.
This can also happen if a splitter in the MD uses nonzero_bits (for
example). I tried to make the splitting code in combine save and restore
the i2dest reg_stat info, but that causes one of the acats tests to fail.
This whole reg_stat thing needs an overhaul, and/or we shouldn't reuse
i2dest for unrelated purposes when splitting.
This patch changes change_zero_ext to do the expected simplifications
itself and not call simplify_gen_*.
PR rtl-optimization/78232
* combine.c (try_combine): Add a big comment about why reusing i2dest
is undesirable.
(change_zero_ext): Do not call simplify_gen_binary, do the
simplifications manually.

Disable unnecessary calls to dwarf2out_decl for the parents of nested
functions. This fixes a libstdc++ build regression on
x86_64-apple-darwin, as these calls used to add duplicate attributes
(for instance DW_AT_inline and DW_AT_object_pointer) to the
corresponding DW_TAG_subprogram DIE.
Bootstrapped and regtested on x86_64-linux.

match.pd transforms (A&C)|(B&~C) to ((A^B)&C)^B, which is fewer
operations if C is not const (and it is not on simple tests at least,
this transform is done very early already).
Various processors have "insert" instructions that can do this, but
combine cannot build those from the xor-and-xor, especially it has no
chance at all to do that if A or B or multiple instructions as well
(on PowerPC, the rl[wd]imi instructions can do this with together with
a rotate, or a simple shift with appropriate C; other ISAs have similar
insns).
This patch makes RTL simplify transform (xor (and (xor A B) C) B) back
to (ior (and A C) (and B ~C)) for constant C (and similar with A instead
of B for that last term).
* simplify-rtx.c (simplify_binary_operation_1): Simplify
(xor (and (xor A B) C) B) to (ior (and A C) (and B ~C)) and

Rename is_immutable to is_static_initializer to try to capture what it
really means. Be more precise about when an address expression, or a
binary expression, can be a static initializer. Don't check whether a
type has pointers when deciding whether an initializer must be
read-write, just check whether it is being used to initialize a global
variable. To make that work set the Translate_context function to NULL
for a global variable with a static initializer.
The effect of this is to let more global variables be initialized
directly, rather than being initialized in the generated init function.
