These tests set large code model with -mcmodel=large or target pragma for
AArch64.  But if GCC is configured with --enable-default-pie, it triggers
"sorry: unimplemented: code model large with -fpic".  Disable PIE to make
avoid the issue.

gcc/testsuite/ChangeLog:

	PR testsuite/70150
	* gcc.dg/tls/pr78796.c (dg-additional-options): Add -fno-pie
	-no-pie for aarch64-*-*.
	* gcc.target/aarch64/pr63304_1.c (dg-options): Add -fno-pie.

If GCC is built with --enable-default-pie, a lot of aapcs64 tests fail

gcc/testsuite/ChangeLog:

	PR testsuite/70150
	* gcc.target/aarch64/aapcs64/aapcs64.exp (additional_flags):
	Add -fno-pie -no-pie.

No planned usage.

	* lib/target-supports.exp (check_compile): Support scanning tree-dumps.

While gcc.dg/plugin/must-tail-call-2.c passes for all targets even
without this, the error message is, for a target like cris-elf that
doesn't implement sibling calls: "error: cannot tail-call: machine
description does not have a sibcall_epilogue instruction pattern"
rather than "error: cannot tail-call: callee returns a structure".
Also, it'd be confusing to exclude must-tail-call-1.c but not
must-tail-call-2.c

	* gcc.dg/plugin/must-tail-call-1.c, gcc.dg/plugin/must-tail-call-2.c:
	Gate on effective target tail_call.

Spot-checked the PDF output for sanity.

	* doc/sourcebuild.texi: Document check_effective_target_tail_call.

The RTL "expand" dump is the first RTL dump, and it also appears to be
the earliest trace of the target having implemented sibcalls.
Including the "," in the pattern searched for, to try and avoid
possible false matches, but there doesn't appear to be any identifiers
or target names nearby so this is just belts and suspenders.  Using
"tail_call" as a shorter and more commonly used term than a derivative
of "sibling calls", and expecting only gcc folks to have heard of
"sibcalls".

	* lib/target-supports.exp (check_effective_target_tail_call): New.

For 32-bit newlib targets (such as cris-elf and pru-elf),
that int32_t is "long int".  See other regexps in the
testsuite matching "aka (long )?int" (with single-quotes
where needed) where the pattern in
allocation-size-multiline-3.c matches plain "int".  Uses the
special syntax recently introduced for multi-line patterns.

testsuite:
	* gcc.dg/analyzer/allocation-size-multiline-3.c: Handle
	int32_t being "long int".

Those multi-line-patterns are literal.  Sometimes a regexp
needs to be matched.  This is a start: just three elements
are supported: "(" ")" and the compound ")?" (and on second
thought, it can be argued that "(...)" alone is not useful).
Note that Tcl "string map" is documented to have the desired
effect: a once-over but no re-recognitions of previously
replaced mapped elements.  Also, drop a doubled "containing".

testsuite:
	* lib/multiline.exp (_build_multiline_regex): Map
	"{re:" to "(", similarly ")?" from ":re?}" and the
	same without question mark.

	* fr.po, sv.po: Update.

This patch updates the IEEE 128-bit types used in libgcc.

At the moment, we cannot build GCC when the target uses IEEE 128-bit long
doubles, such as building the compiler for a native Fedora 36 system.  The
build dies when it is trying to build the _mulkc3.c and _divkc3 modules.

This patch changes libgcc to use long double for the IEEE 128-bit base type if
long double is IEEE 128-bit, and it uses _Float128 otherwise.  The built-in
functions are adjusted to be the correct version based on the IEEE 128-bit base
type used.

While it is desirable to ultimately have __float128 and _Float128 use the same
internal type and mode within GCC, at present if you use the option
-mabi=ieeelongdouble, the __float128 type will use the long double type and not
the _Float128 type.  We get an internal compiler error if we combine the
signbitf128 built-in with a long double type.

I've gone through several iterations of trying to fix this within GCC, and
there are various problems that have come up.  I developed this alternative
patch that changes libgcc so that it does not tickle the issue.  I hope we can
fix the compiler at some point, but right now, this is preventing people on
Fedora 36 systems from building compilers where the default long double is IEEE
128-bit.

In the toolchain convention, we describe -mfpu= as:

"Selects the allowed set of basic floating-point instructions and
registers. This option should not change the FP calling convention
unless it's necessary."

Though not explicitly stated, the rationale of this rule is to allow
combinations like "-mabi=lp64s -mfpu=64".  This will be useful for
running applications with LP64S/F ABI on a double-float-capable
LoongArch hardware and using a math library with LP64S/F ABI but native
double float HW instructions, for a better performance.

And now a case in Linux kernel has again proven the usefulness of this
kind of combination.  The AMDGPU DCN kernel driver needs to perform some
floating-point operation, but the entire kernel uses LP64S ABI.  So the
translation units of the AMDGPU DCN driver need to be compiled with
-mfpu=64 (the kernel lacks soft-FP routines in libgcc), but -mabi=lp64s
(or you can't link it with the other part of the kernel).

Unfortunately, currently GCC uses TARGET_{HARD,SOFT,DOUBLE}_FLOAT to
determine the floating calling convention.  This causes "-mfpu=64"
silently allow using $fa* to pass parameters and return values EVEN IF
-mabi=lp64s is used.  To make things worse, the generated object file
has SOFT-FLOAT set in the eflags field so the linker will happily link
it with other LP64S ABI object files, but obviously this will lead to
bad results at runtime.  And for now all loongarch64 CPU models (-march
settings) implies -mfpu=64 on by default, so the issue makes a single
"-mabi=lp64s" option basically broken (fortunately most projects for eg
the Linux kernel have used -msoft-float which implies both -mabi=lp64s
and -mfpu=none as we've recommended in the toolchain convention doc).

The fix is simple: use TARGET_*_FLOAT_ABI instead.

I consider this a bug fix: the behavior difference from the toolchain
convention doc is a bug, and generating object files with SOFT-FLOAT
flag but parameters/return values passed through FPRs is definitely a
bug.

This showed up as dynamic icount regression in SPEC 531.deepsjeng with upstream
gcc (vs. gcc 12.2). gcc was resorting to synthetic multiply using shift+add(s)
even when multiply had clear cost benefit.

Bisected this to f90cb392 ("RISC-V: costs: support shift-and-add in
strength-reduction"). The intent was to optimize cost for
shift-add-pow2-{1,2,3} corresponding to bitmanip insns SH*ADD, but ended
up doing that for all shift values which seems to favor synthezing
multiply among others.

The bug itself is trivial, IN_RANGE() calling pow2p_hwi() which returns bool
vs. exact_log2() returning power of 2.

This fix also requires update to the test introduced by the same commit
which now generates MUL vs. synthesizing it.

E.g., the case int f(int x) { return x >= 0 ? x : 0; }
the current asm output in rv64gc_zba_zbb

 max a0,a0,rtmp

could be optimized into

 max a0,a0,zero
