Bug ID: 77882
Summary: [Aarch64, ARM64] Add 'naked' function attribute
Product: gcc
Version: 6.1.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: christophe.monat at st dot com
Target Milestone: ---
With the following code fragment aarch64-attribute-naked.c :
void
__attribute__((naked))
dealwithit()
{
// Stuff removed above, below we assume that the 'naked' attribute
// does the job and does not generate the usual 'ret' instruction
asm("eret"::);
}
$ aarch64-linux-gnu-gcc -S aarch64-attribute-naked.c
aarch64-attribute-naked.c:4:1: warning: 'naked' attribute directive ignored
[-Wattributes]
I have tried with a gcc-6.1.1, but simply as an example, this feature has never
been ported to Aarch64, I think.
As this attribute is supported for the legacy ARM target, it would be nice it
the Aarch64 compiler could support it.
