Subject: [PATCH 10/25] gnu-efi: fix lib/ia64/setjmp.S IA-64 build failure
|
|
|
cfe30e |
|
|
|
cfe30e |
The build failed as:
|
|
|
cfe30e |
lib/ia64/setjmp.S:171: Error: Unknown opcode `ldf.nt1 f26=[r10],8'
|
|
|
cfe30e |
lib/ia64/setjmp.S:178: Error: Operand 1 of `ldf.fill.nt1' should be a floating-point register
|
|
|
cfe30e |
|
|
|
cfe30e |
The change syncs longjmp definition with
|
|
|
cfe30e |
edk2/EdkCompatibilityPkg/Foundation/Library/EdkIIGlueLib/Library/BaseLib/Ipf/setjmp.s
|
|
|
cfe30e |
pulling in:
|
|
|
cfe30e |
- branch in the end of function
|
|
|
cfe30e |
- registers used wrong instruction for float restore
