Makefile: Remove unnecessary dependencies

2024-04-08T04:38:20Z

The rule included from auto.conf.cmd adds a dependency on every Kconfig file, so these two Kconfig files do not need to be specified again here. Signed-off-by: Samuel Holland Reviewed-by: Anup Patel Tested-by: Anup Patel

Makefile: Respect manual changes to .config

2024-04-07T06:35:37Z

The .config file may be manually edited or copied from another location. Since genconfig.py is responsible for generating auto.conf (the Makefile fragment) and autoconf.h (the C header) from .config, it must be run any time .config changes, not just when running menuconfig.

Makefile: check for --exclude-libs

2024-02-05T11:04:44Z

While writing to the dynsym is futile, the --exclude-libs options is not recognized by all linkers (e.g. riscv64-elf-ld.bfd). Signed-off-by: Leon M. Busch-George Reviewed-by: Anup Patel

Makefile: don't pass -mstrict-align if not supported

2024-02-05T10:30:54Z

Support for that option will be added in LLVM 18: https://github.com/llvm/llvm-project/commit/23ce5368409c760f3dd49d0f17f34772b0b869d8 Clang 17.0.6, however, will error when passed the `-mstrict-align` flag. We should only use the flag if it is supported. Signed-off-by: Kalle Wachsmuth Reviewed-by: Anup Patel Reviewed-by: Xiang W

Makefile: Add --exclude-libs ALL to avoid .dynsym

2023-10-06T03:51:24Z

Since everything is statically linked, we don't need to expose symbols for dynamic linking. For a default build this saves about 2 KiB of useless read only data in .dynsym, .dynstr, .hash, .gnu.hash sections. Signed-off-by: Vivian Wang Reviewed-by: Anup Patel

Makefile: Fix grep warning

2023-08-22T07:56:03Z

grep (at least my version, grep-3.8-3.fc38.x86_64) warns with "grep: warning: stray \ before -". Fix the warning by making the command line input to grep less ambiguous. Signed-off-by: Andrew Jones Reviewed-by: Anup Patel

Makefile: Dereference symlinks on install

2023-05-22T03:22:57Z

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.

Makefile: Add missing .dep files for fw_*.elf.ld

2023-02-08T11:06:55Z

Since we don't currently create these, changes to fw_base.ldS do not cause the preprocessed fw_*.elf.ld files to be rebuilt, and thus incremental builds can end up failing with missing symbols if crossing the recent commits that introduced _fw_rw_offset and then replaced it with _fw_rw_start.
