Unicorn: allow building in EFI environment.
Browse files Browse the repository at this point in the history 
With some restrictions:
- no timeout support in uc_emu_start

Tiano uses its own custom build environment.

Every target emulator is built as a separate lib. Today, only
UnicornLibX86, UnicornLibArm64, UnicornLibRV64 and
UnicornLibRV32 are provided.

Building:
export GCC5_RISCV64_PREFIX=riscv64-linux-gnu build -a RISCV64 -t GCC5 -p unicorn/efi/UnicornPkg.dsc -b RELEASE
export GCC5_AARCH64_PREFIX=aarch64-linux-gnu build -a AARCH64 -t GCC5 -p unicorn/efi/UnicornPkg.dsc -b RELEASE

You get UnicornSampleX86, UnicornSampleArm64 and UnicornSampleRV.
The latter shows how it's possible to link against multiple target
emu libs.

Ran into an AArch64 issue where due to LTO the build of
UnicornSameArm64 takes forever and then bombs out complaining
about missing __ashrti3. This remains to be investigated,
and a w/a is to modify Conf/tools_def.txt to avoid LTO.
