Bug #: 50187
Summary: Interrupt handler attribute for x86/x86_64
Classification: Unclassified
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: enhancement
Priority: P3
Component: inline-asm
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: christian.gnu@juner.de
I think it would be nice to have a function attribute that tells gcc to omit
the function prologue/epilogue, to be able to write tings such as interrupt
handlers. See the description of different compiler implementations here:
