* ArmPkg: introduce ASM_FUNC, MOV32/MOV64 and ADRL/LDRL macrosArd Biesheuvel2016-08-111-1/+19
| | | | | | | | | | | | | | | | This introduces the ASM_FUNC() macro to annotate function entry points in assembler files. This allows us to add additional metadata that marks a function entry point as a function, and allows us to emit a .section directive for each function, which makes it possible for the linker to drop unreferenced code. In addition, introduce a couple of utility macros that we can use to clean up the code.

* ArmPkg/AsmMacroIoLibV8: remove undocumented assumption from ELx macrosArd Biesheuvel2016-03-221-8/+8
| | | | | | | | | | | | | | | The macros EL1_OR_EL2() and EL1_OR_EL2_OR_EL3() allow conditional execution of assembly sequences based on the current exception level, by jumping to caller supplied labels 1f, 2f or 3f. However, the jump to 1f is actually a fallthrough, which means the EL1 code needs to follow right after the macro invocation, and the 1f label is ignored. So let's fix this by making all jumps explicit.

| | | | | | | | | | | | The SetPrimaryStack and InitializePrimaryStack macros are no longer used now that we removed support for ArmPlatformGlobalVariableLib. So remove the various versions of them.

* ArmPkg: Replace single dead loop.Olivier Martin2014-03-011-12/+12
| | | | | | | | | | | | | | Several assembler macros use a loop at the label "dead" to trap an error. This is difficult to debug as there is no indication of how one arrived at the loop. This change replaces dead with distinct loops locally in the macro, which means the cause of the hang is detectable to the debugger.
