2024-08-24Makefile: fix OPENSBI_VERSION_GIT build with submodulesDaniel Henrique Barboza1-1/+10
When building OpenSBI via a submodule, OPENSBI_VERSION_GIT can be left unset in case '.git' isn't a dir. This is the case when building OpenSBI as a QEMU submodule: $ cat .git gitdir: ../../.git/modules/roms/opensbi As a result, building OpenSBI tag v1.5.1 in QEMU will result in a binary that will have "OpenSBI v1.5" as a banner. Use "git rev-parse --git-dir" instead of checking if '.git' is a dir to detect if the current dir is a git repo.

2023-05-22Makefile: Dereference symlinks on installFilip Filmar1-4/+4
Adds the `-L` flag (follow symlinks) to the `cp` commands used to install `libsbi.a` and `include/sbi/*`. This should make no difference in regular compilation. However, it does make a difference when compiling with bazel. Namely, bazel's sandboxing will turn all the source files into symlinks. After installation with `cp` the destination files will be symlinks pointing to the sandbox symlinks. As the sandbox files are removed when compilation ends, the just-copied symlinks become dangling symlinks. The resulting include files will be unusable due to the dangling symlink issues. Adding `-L` when copying ensures that the files obtained by executing the `install` targets are always dereferenced to files, rather than symlinks, eliminating this issue.

2021-07-27Makefile: Manually forward RELAX_FLAG to the assembler when linking with LLDBin Meng1-0/+5
When generating code with -mno-relax, GCC puts .option norelax in the generated assembly, and so doesn’t bother passing on -mno-relax to the assembler.

This is an old GCC bug that was fixed [1] recently.

This is intended to mirror the Linux kernel. Building with CC=clang will use Clang as the compiler but default to using the existing binutils. Building with LLVM=1 will default to using Clang and LLVM binutils. Whilst GCC will accept the -N linker option and forward it on to the linker, Clang will not, and so in order to support both compilers we must use -Wl, to forward it to the linker as is required for most other linker options. Note that there is currently a bug when using Clang as the compiler and riscv64-linux-gnu-ld as the linker for FW_PIC=y. At first glance this appears to be a bug in GNU binutils, but this could also be Clang or OpenSBI at fault in some subtle way. Thus, for now, advise that this combination be avoided.

2020-02-06makefile: add support for building on macOSAlex Richardson1-3/+10
On macOS the readlink command does not include a -f flag. Instead default to using GNU readlink (which is often installed as greadlink). Signed-off-by: Alex Richardson <Alexander.Richardson@cl.cam.ac.uk> Signed-off-by: Anup Patel <anup.patel@wdc.com>
2020-01-08build: Use -ffreestandingKhem Raj1-1/+1
this is a stand-alone/baremetal application, therefore demanding -ffreestanding would help it compile with hosted toolchains e.g. ( linux toolchains ), it also ensures that it won't be using platform optimizations like inlining mem* str* functions which gcc might decide especially with wrapper string functions in opensbi code Signed-off-by: Khem Raj <raj.khem@gmail.com> Reviewed-by: Anup Patel <anup.patel@wdc.com>
2019-10-02Makefile: Minor fix in OPENSBI_VERSION_GITAnup Patel1-1/+1
Currently, if someone has forked OpenSBI repo quite sometime back and this fork is not having updated tags from upstream riscv/opensbi repo then "git describe" command can fail. To tackle this, we redirect error output of "git describe" to /dev/null. Signed-off-by: Anup Patel <anup.pate@wdc.com> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
2019-08-19Include `git describe` in OpenSBIPalmer Dabbelt1-0/+4
OpenSBI includes a version, but that is only updated when tagged. For users that are using the git releases we instead end up with an ambiguous version number, which makes it hard to figure out what everyone is using. This patch checks for a git directory and prints out the result of `git describe`, which is a mix of pretty and unambiguous.
