2020-02-03xcompile: Disable null pointer optimizationsJacob Garber
According to the C standard, accessing the NULL pointer (memory at address zero) is undefined behaviour, and so GCC is allowed to optimize it out. Of course, accessing this memory location is sometimes necessary, so this optimization can be disabled using -fno-delete-null-pointer-checks. This is already done in coreboot, but adding it to xcompile will also disable it for all the payloads. For example, coreinfo compiled with LTO libpayload crashes when this flag isn't set, presumably because the compiler is optimizing something out that it shouldn't.

2019-11-20Remove MIPS architectureJulius Werner
The MIPS architecture port has been added 5+ years ago in order to support a Chrome OS project that ended up going nowhere. No other board has used it since and nobody is still willing or has the expertise and hardware to maintain it. We have decided that it has become too much of a mainenance burden and the chance of anyone ever reviving it seems too slim at this point. This patch eliminates all MIPS code and MIPS-specific hacks.

For x64 and x86_32 configurations, apply the -march flag to both GCC and Clang flags. This solves the problem of Clang-compiled coreboot failing due to Clang emitting SSE instructions for code that is executed while SSE is not enabled. This patch takes functionality targeted for GCC configurations and moves it down a few lines, modifying CFLAGS instead of GCC_CFLAGS in order that it applies to both GCC and Clang.

2019-03-06pci_drivers/cpu_drivers: Fix constructed arrays on x86_64Patrick Rudolph
The __pci_driver and __cpu_driver uses variable length arrays which are constructed by the linker at build-time. The linker always place the structs at 16-byte boundary, as per "System V ABI". That's not a problem on x86, as the struct is exactly 16 Bytes in size. On other platforms, like x86_64 it breaks, because the default data alignment isn't SysV compatible. Set -malign-data=abi to make x86_64 gcc use the SysV psABI. Fixes broken __pci_driver and __cpu_driver on x86_64.

2017-06-25xcompile: Fix clang compiler runtime detectionStefan Reinauer
clang, like gcc, needs a compiler runtime library. Unlike gcc, it can use either its own runtime library (compiler-rt), or gcc's version (libgcc). Also unlike gcc, the version of clang that is currently part of our reference toolchain does not provide the necessary versions of compiler-rt for all platforms we support. Hence, for now, use libgcc even on clang builds. This patch allows switching between the two, but switching to compiler-rt will break clang builds, unless someone fixes our reference toolchain to provide libclang_rt.builtins-${ARCH}.a for each of our supported platforms.

2016-01-15xcompile: Add core count to .xcompileMartin Roth
I think these four methods should cover most operating systems, with many supporting several of the methods. If we don't find anything, we're not any worse off than we were before. The big issue would be if we get an incorrect value.

2016-01-14xcompile: More updates on ARM64 Erratum flagsMartin Roth
I tried to handle the checking for the config flag internal to xcompile, but the config flags don't appear to have been loaded into the environment by make at that point. This does update the if to check if the flag is even set before putting anything into .xcompile though. If the LDFLAG isn't set, there's no point in appending anything. Also removes the LP version of the erratum config flag, which was a copy/paste mistake from $(CONFIG_LP_COMPILER_GCC).

2016-01-07xcompile: Quote variables to prevent globbing and splitting.Martin Roth
Quoting variables prevents word splitting and glob expansion, and prevents the script from breaking when input contains spaces, line feeds, glob characters and such.

2016-01-07xcompile: use $() instead of backticksMartin Roth
While the backtick syntax isn't actually deprecated, the $() syntax is preferred. Since both styles were being used in this script, settle on the new standard for all cases.

2016-01-07xcompile: Put compiler variables outside of 'if' to allow checkingMartin Roth
In order to be able to check the compiler versions, we need to be able to access the compiler variables. Move the original assignments outside of the GCC check, and assign either the GCC or CLANG compiler to the actual CC_ environment variable later. This ends up with the same value set, while allowing the compiler versions to be checked.
