[Xen-devel] Hypervisor compilation for arm without debug=y

[Andrii Anisov <andrii.anisov@xxxxxxxxxxxxxxx>]

Hello,

I tried to get hypervisor built without debug=y option.

Unfortunately built binary doesn't boot.

I've localized a problem and get a workaround for it:

diff --git a/xen/arch/arm/mm.c b/xen/arch/arm/mm.c

index d1290cd..aa8e057 100644

--- a/xen/arch/arm/mm.c

+++ b/xen/arch/arm/mm.c

@@ -332,7 +332,7 @@ void __cpuinit setup_virt_paging(void)

 

 /* Boot-time pagetable setup.

  * Changes here may need matching changes in head.S */

-void __init setup_pagetables(unsigned long boot_phys_offset, paddr_t xen_paddr)

+void __attribute__((optimize("-fno-omit-frame-pointer"))) __init setup_pagetables(unsigned long boot_phys_offset, paddr_t xen_paddr)

 {

     unsigned long dest_va;

     lpae_t pte, *p;

Is it a known issue? Is there a better solution for it?

I work with 4.3 release, build with gcc version 4.6.3 (Ubuntu/Linaro 4.6.3-1ubuntu5) 

Sincerely,
Andrii Anisov.
