Hey guys,
I’m having some issues building OVMF on OS X 10.9 with the latest dev tools.
I’m running Xcode 5.1.1, with the “Late June” Command Line Tools.
$ clang --version
Apple LLVM version 5.1 (clang-503.0.40) (based on LLVM 3.4svn)
Target: x86_64-apple-darwin13.0.0
Thread model: posix
Issue #1
$ build -p OvmfPkg/OvmfPkgX64.dsc

Error 1
This is the code in question:
DoReturn:
pushq %rax
movabsq ASM_PFX(mDoFarReturnFlag), %rax
cmpq $0, %rax # Check if need to do far return instead of IRET
popq %rax
jz DoIret
pushq %rax
movq %rsp, %rax # save old RSP to rax
movq 0x20(%rsp), %rsp
pushq 0x10(%rax) # save CS in new location
pushq 0x8(%rax) # save EIP in new location
pushq 0x18(%rax) # save EFLAGS in new location
movq (%rax), %rax # restore rax
popfq # restore EFLAGS
.byte 0x48 # prefix to composite "retq" with next "retf"
retf # far return
I changed the `retf` to a `ret` to get it to assemble for now.
Issue #2
Next issue is with the ACPI tables:

I’m not familiar with compiling ASL, so I’m not sure what’s going on here, but
it seems like a bad invocation of `iasl`. I installed the `acpica` package from
homebrew, which contains `iasl`.
$ iasl -v

The build rule for ASL files looks like this:

Trim --asl-file -o $(OUTPUT_DIR)(+)${s_dir}(+)${s_base}.i -i
$(INC_LIST) ${src}

"$(ASL)" $(ASL_FLAGS) $(ASL_OUTFLAGS)${dst}
$(OUTPUT_DIR)(+)${s_dir}(+)${s_base}.iii
Any ideas?

Not sure if the main is actually required for this guy? Again, not too familiar
with ACPI, but just defining a dummy main function in each of the `aslc` files
(it happens with each of them) gets past there. I suspect this is a change in
behaviour with clang, I remember having a similar issue with some freestanding
Rust code.

Wondering if this is a result of the `ret` instruction change I made earlier.
That’s as far as I’m able to get so far. Any help is appreciated :)
Thanks,
