Register 18 is used as a clobber register, and must be stored - when entering a fast_interrupt. Before this fix, register 18 was only saved - if it was used directly in the interrupt function. - -However, if the fast_interrupt function called a function that used -r18, the register would not be saved, and thus be mangled -upon returning from the interrupt. - -Changelog - -2014-02-27 Klaus Petersen <klauspetersen@gmail.com> - - * gcc/config/microblaze/microblaze.c: Check for fast_interrupt in - microblaze_must_save_register. - -Signed-off-by: Klaus Petersen <klauspetersen@gmail.com> -Signed-off-by: David Holsgrove <david.holsgrove@xilinx.com> ---- - gcc/config/microblaze/microblaze.c | 2 +- - 1 file changed, 1 insertion(+), 1 deletion(-) - -diff --git a/gcc/config/microblaze/microblaze.c b/gcc/config/microblaze/microblaze.c -index cbe8cb7..6f0b4f4 100644 ---- a/gcc/config/microblaze/microblaze.c -+++ b/gcc/config/microblaze/microblaze.c -@@ -1967,7 +1967,7 @@ microblaze_must_save_register (int regno) - { - if (df_regs_ever_live_p (regno) - || regno == MB_ABI_MSR_SAVE_REG -- || (interrupt_handler -+ || ((interrupt_handler || fast_interrupt) - && (regno == MB_ABI_ASM_TEMP_REGNUM - || regno == MB_ABI_EXCEPTION_RETURN_ADDR_REGNUM))) - return 1; --- -2.7.4 - |
