From: Piotr Trojanek <troja...@adacore.com>
Queries that ultimately examine the same field of an AST
node (e.g. Nkind) are visibly more efficient when inlined.
In particular, routines Is_Body_Or_Package_Declaration and Is_Body can
apparently be inlined into a single Nkind membership test.
This patch fixes some of the performance lost with the recent changes,
which increased the number of calls to Is_Body_Or_Package_Declaration
(as it is typically used to prevent AST search from climbing too far).
However, it should be generally beneficial to inline routines like this.
gcc/ada/
* sem_aux.ads (Is_Body): Annotate with Inline.
* sem_util.ads (Is_Body_Or_Package_Declaration): Likewise.
Tested on x86_64-pc-linux-gnu, committed on master.
