This is a first step towards enabling the sincos optimization in Ada.
The issue this patch solves is that sincos takes the type to be looked
up with mathfn_built_in from variables or temporaries passed as
arguments to SIN and COS intrinsics. In Ada, different float types
may be used but, despite their representation equivalence, their
distinctness causes the optimization to be skipped, because they are
not the types that mathfn_built_in expects.
This patch introduces a function that maps intrinsics to the type
they're associated with, and uses that type, obtained from the
intrinsics used in calls to be optimized, to look up the correspoding
CEXPI intrinsic.
For the sake of defensive programming, when using the type obtained
from the intrinsic, it now checks that, if different types are found
for the used argument, or for other calls that use it, that the types
are interchangeable.

GCC has a target hook TARGET_LIBC_HAS_FUNCTION, which tells the compiler
which functions it can expect to be present in libc.
The default target hook does not include the sincos functions.
The nvptx port of newlib does include sincos and sincosf, but not sincosl.
The target hook TARGET_LIBC_HAS_FUNCTION does not distinguish between sincos,
sincosf and sincosl, so if we enable it for the sincos functions, then for
test.c:
...
long double x, a, b;
int main (void) {
x = 0.5;
a = sinl (x);
b = cosl (x);
printf ("a: %f\n", (double)a);
printf ("b: %f\n", (double)b);
return 0;
}
...
we introduce a regression:
...
$ gcc test.c -lm -O2
unresolved symbol sincosl
collect2: error: ld returned 1 exit status
...
Add a type argument to target hook TARGET_LIBC_HAS_FUNCTION_TYPE, and use it
in nvptx_libc_has_function_type to enable sincos and sincosf, but not sincosl.
Build and reg-tested on x86_64-linux.
Build and tested on nvptx.

As mentioned in the PR, we generate a useless movzbl insn before lock cmpxchg.
The problem is that the builtin for the char/short cases has the arguments
promoted to int and combine gives up, because the instructions have
MEM_VOLATILE_P arguments and recog in that case doesn't recognize anything
when volatile_ok is false, and nothing afterwards optimizes the
(reg:SI a) = (zero_extend:SI (reg:QI a))
... (subreg:QI (reg:SI a) 0) ...
The following patch fixes it at expansion time, we already have a function
that is meant to undo the promotion, so this just adds the very common case
to that.

This patch introduces a new builtin named __builtin_bswap128 on targets
where TImode is supported, i.e. 64-bit targets only in practice. The
implementation simply reuses the existing double word path in optab, so
no routine is added to libgcc (which means that you get two calls to
_bswapdi2 in the worst case).
gcc/ChangeLog:
* builtin-types.def (BT_UINT128): New primitive type.
(BT_FN_UINT128_UINT128): New function type.

The following testcase FAILs with -O2 -fcompare-debug, but the reason isn't
that we'd emit different code based on -g or non-debug, but rather that
we emit different code depending on whether -w is used or not (or e.g.
-Wno-stringop-overflow or whether some other pass emitted some other warning
already on the call).
Code generation shouldn't depend on whether we emit a warning or not if at
all possible.
The following patch punts (i.e. doesn't optimize the strnlen call to a
constant value) if we would emit the warning if it was enabled.
In the PR there is an alternate patch which does optimize the strnlen call
no matter if we emit the warning or not, though I think I prefer the version
below, e.g. the strnlen call might be crossing field boundaries, which is in
strict reading undefined, but I'd be afraid people do that in the real
world programs.

C2x adds <float.h> constants FLT_NORM_MAX, DBL_NORM_MAX and
LDBL_NORM_MAX. These are for the maximum "normalized" finite
floating-point number, where the given definition of normalized is
that all possible values with MANT_DIG significand digits (leading one
not zero) can be represented with that exponent. The effect of that
definition is that these macros are the same as the corresponding MAX
macros for all formats except IBM long double, where the NORM_MAX
value has exponent 1 smaller than the MAX one so that all 106 digits
can be 1.
This patch adds those macros to GCC. They are only defined for float,
double and long double; C2x does not include such macros for DFP
types, and while the integration of TS 18661-3 into C2x has not yet
occurred, the draft proposed text does not add them for the _FloatN /
_FloatNx types (where they would always be the same as the MAX
macros).
Bootstrapped with no regressions on x86_64-pc-linux-gnu. Also tested
compilation of the new test for powerpc-linux-gnu to confirm the check
of LDBL_NORM_MAX in the IBM long double case does get properly
optimized out.

This was first submitted many years ago
https://gcc.gnu.org/ml/gcc-patches/2010-10/msg02468.html
The command line option -fcallgraph-info is added and makes the
compiler generate another output file (xxx.ci) for each compilation
unit (or LTO partitoin), which is a valid VCG file (you can launch
your favorite VCG viewer on it unmodified) and contains the "final"
callgraph of the unit. "final" is a bit of a misnomer as this is
actually the callgraph at RTL expansion time, but since most
high-level optimizations are done at the Tree level and RTL doesn't
usually fiddle with calls, it's final in almost all cases. Moreover,
the nodes can be decorated with additional info: -fcallgraph-info=su
adds stack usage info and -fcallgraph-info=da dynamic allocation info.

In LTO mode, if static library and dynamic library contains same
function and both libraries are passed as arguments, linker will link
the function in dynamic library no matter the sequence. This patch
will output LTO symbol node as UNDEF if BUILT_IN_NORMAL function FNDECL
is a math function, then the function in static library will be linked
first if its sequence is ahead of the dynamic library.

We were shoe-horning all built-in enumerations (including frontend
and target-specific ones) into a field of type built_in_function. This
was accessed as either an lvalue or an rvalue using DECL_FUNCTION_CODE.
The obvious danger with this (as was noted by several ??? comments)
is that the ranges have nothing to do with each other, and targets can
easily have more built-in functions than generic code. But my patch to
make the field bigger was the straw that finally made the problem visible.
This patch therefore:
- replaces the field with a plain unsigned int
- turns DECL_FUNCTION_CODE into an rvalue-only accessor that checks
that the function really is BUILT_IN_NORMAL
- adds corresponding DECL_MD_FUNCTION_CODE and DECL_FE_FUNCTION_CODE
accessors for BUILT_IN_MD and BUILT_IN_FRONTEND respectively
- adds DECL_UNCHECKED_FUNCTION_CODE for places that need to access the
underlying field (should be low-level code only)
- adds new helpers for setting the built-in class and function code
- makes DECL_BUILT_IN_CLASS an rvalue-only accessor too, since all
assignments should go through the new helpers
