From: Mikael Morin <mik...@gcc.gnu.org>
The documentation in this patch was partly reworded, compared
to the previous version posted at:
https://gcc.gnu.org/pipermail/gcc-patches/2024-August/660607.html
The rest of the patch is unchanged, just rebased to a more recent
master.
Joseph is in CC as I need a ack for the new option.
Regression-tested on x86_64-pc-linux-gnu.
OK for master?

Introduce the -finline-intrinsics flag to control from the command line
whether to generate either inline code or calls to the functions from the
library, for the MINLOC and MAXLOC intrinsics.
The flag allows to specify inlining either independently for each intrinsic
(either MINLOC or MAXLOC), or all together. For each intrinsic, a default
value is set if none was set. The default value depends on the optimization
setting: inlining is avoided if not optimizing or if optimizing for size;
otherwise inlining is preferred.
There is no direct support for this behaviour provided by the .opt options
framework. It is obtained by defining three different variants of the flag
(finline-intrinsics, fno-inline-intrinsics, finline-intrinsics=) all using
the same underlying option variable. Each enum value (corresponding to an
intrinsic function) uses two identical bits, and the variable is initialized
with alternated bits, so that we can tell whether the value was set or not
by checking whether the two bits have different values.

gcc/ChangeLog:
* flag-types.h (enum gfc_inlineable_intrinsics): New type.
gcc/fortran/ChangeLog:
* invoke.texi(finline-intrinsics): Document new flag.
* lang.opt (finline-intrinsics, finline-intrinsics=,
fno-inline-intrinsics): New flags.
* options.cc (gfc_post_options): If the option variable controling
the inlining of MAXLOC (respectively MINLOC) has not been set, set
it or clear it depending on the optimization option variables.
* trans-intrinsic.cc (gfc_inline_intrinsic_function_p): Return false
if inlining for the intrinsic is disabled according to the option
variable.

+Prefer generating inline code over calls to libgfortran functions to implement
+intrinscs.
+
+Usage of intrinsics can be implemented either by generating a call to the
+libgfortran library function implementing it, or by directly generating the
+implementation code inline. For most intrinsics, only a single of those
+variants is available and there is no choice of implementation. For some of
+them, however, both are available, and for them the @code{-finline-intrinsics}
+flag permits the selection of inline code generation in its positive form, or
+library call generation in its negative form @code{-fno-inline-intrinsics}.
+With @code{-finline-intrinsics=...} or @code{-fno-inline-intrinsics=...}, the
+choice applies only to the intrinsics present in the comma-separated list
+provided as argument.
+
+For each intrinsic, if no choice of implementation was made through either of
+the flag variants, a default behaviour is chosen depending on optimization:
+library calls are generated when not optimizing or when optimizing for size;
+otherwise inline code is preferred.
+
+The set of intrinsics allowed as argument to @code{-finline-intrinsics=}
+is currently limited to @code{MAXLOC} and @code{MINLOC}. The effect of
+the flag is moreover limited to calls of those intrinsics without
+@code{DIM} argument and with @code{ARRAY} of a non-@code{CHARACTER} type.
+The case of rank-1 argument and @code{DIM} argument present, i.e.
+@code{MAXLOC(A(:),DIM=1)} or @code{MINLOC(A(:),DIM=1)} is inlined
+unconditionally for numeric rank-1 array argument @code{A}.
