Hi
The reference implementation for Objective-C provides the SEL
typedef (although it is also available from <objc/objc.h>).
tested on x86_64-darwin, x86_64-linux-gnu
pushed
thanks
Iain
gcc/objc/ChangeLog:
* objc-act.c (synth_module_prologue): Get the SEL identifier.
* objc-act.h (enum objc_tree_index): Add OCTI_SEL_NAME.
(objc_selector_name): New.
(SEL_TYPEDEF_NAME): New.
* objc-gnu-runtime-abi-01.c
(gnu_runtime_01_initialize): Initialize SEL typedef.
* objc-next-runtime-abi-01.c
(next_runtime_01_initialize): Likewise.
* objc-next-runtime-abi-02.c
gcc/testsuite/ChangeLog:
* obj-c++.dg/SEL-typedef.mm: New test.
* objc.dg/SEL-typedef.m: New test.
