[Bug c/91937] _Generic Feature Expansion
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=91937 --- Comment #2 from Srinath Parvathaneni --- I'm using _Generic to create polymorphic implementations of MVE intrinsics. MVE have more than 50 data types (combinations) and intrinsics with more upto 5 arguments. So on nesting a call to just two intrinsics is expanding to more than 4000 lines. The nesting of calls increases pre-processor output exponentially and slowing down the compiler. I'm expecting "_Generic" could expand only to exactly matching combination which would optimize the pre-processor output file size.
[Bug c/91937] New: _Generic Feature Expansion
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=91937
Bug ID: 91937
Summary: _Generic Feature Expansion
Product: gcc
Version: 9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: srinath.parvathaneni at arm dot com
Target Milestone: ---
Created attachment 46983
--> https://gcc.gnu.org/bugzilla/attachment.cgi?id=46983=edit
Preprocessor output
On compiling the following test.c with gcc and checking the preprocessor file.
In C, for a macro using "_Generic" feature, "_Generic" expands completely but
not just for the matching case. This expansion is increasing the pre-processor
file size enormously in case of nested macros and slowing down the compiler.
$ gcc -v
