ArmVirtPkg/PrePiUniCoreRelocatable CLANG38: work around build issues The self-relocating PrePi module that is used by the ArmVirtQemuKernel and ArmVirtXen targets runs the linker in PIE mode so that it emits dynamic relocations into the final image in a way that permits the module to relocate itself into place before calling into the C code. When building these targets using the CLANG38 toolchain, we switch from the BFD to the GOLD linker, which behaves a bit differently when building PIE executables, and insists on emitting GOT indirected symbol references throughout, which means a) that we end up with absolute addresses (which need to be fixed up at load time) for no good reason, and b) we have to add support for handling GOT entries to GenFw if we want to convert them into PE/COFF. So instead, let's emit a shared library. Since the ELF image only serves as the input to GenFw, this does not lead to any loss of functionality, although it does require the -Bsymbolic linker option to be added to ensure that no symbol based dynamic relocations are emitted (which would, e.g., permit lazy binding for shared libraries). So for all other toolchains, the linker option changes are a no-op. Then, we have to convince CLANG38/GOLD that there is no need to refer to symbols via a GOT entry. This is done by forcing hidden visibility for all symbols in all components that make up the PrePi SEC module: this informs the linker that a symbol is never exported or preempted, making it safe to refer to it directly from anywhere in the code, rather than indirectly via a GOT entry.

ArmVirtPkg: use protocol-based DevicePathLib instance for most DXE modules Port OvmfPkg commit 5c3481b0b611e to ArmVirtPkg. Some explanation should be in order (because 5c3481b0b611e doesn't offer any): - The UefiDevicePathLibDevicePathProtocol instance uses the Device Path Utilities Protocol, produced by DevicePathDxe, for formatting and parsing the textual device path representation. This allows for a lighter weight lib instance that gets linked into several DXE modules. In comparison, the more standalone UefiDevicePathLib instance includes the formatting and parsing routines in every client module. - The DXE core needs DevicePathLib before it dispatches DevicePathDxe, so it needs to stick with the standalone instance. - DevicePathDxe itself also needs the standalone instance, for implementing the protocol. - The DXE-phase PCD driver, "MdeModulePkg/Universal/PCD/Dxe/Pcd.inf", depends on DevicePathLib via UefiLib and DxeServicesLib at the least; so with this update, it inherits a dependency on the protocol. In reverse, DevicePathDxe depends on the PCD Protocol, via PcdLib. The cycle is broken by using BasePcdLibNull in DevicePathDxe. That restricts it to FixedAtBuild, Patch, and FeatureFlag PCDs, but that's fine. Example space savings (using ArmVirtQemu and the GCC5 toolchain): - NOOPT: 187KB in FVMAIN, 12KB in FVMAIN_COMPACT - DEBUG: 147KB in FVMAIN, 20KB in FVMAIN_COMPACT - RELEASE: 123KB in FVMAIN, 17KB in FVMAIN_COMPACT Cc: Ard Biesheuvel <ard.biesheuvel@linaro.org> Cc: Julien Grall <julien.grall@linaro.org> Ref: https://bugzilla.tianocore.org/show_bug.cgi?id=940 Contributed-under: TianoCore Contribution Agreement 1.1 Signed-off-by: Laszlo Ersek <lersek@redhat.com> Reviewed-by: Ard Biesheuvel <ard.biesheuvel@linaro.org>
