Heiko Stuebner 49b290e430 riscv: prevent compressed instructions in alternatives ... Instructions are opportunistically compressed by the RISC-V assembler when possible, but in alternatives-blocks both the old and new content need to be the same size, so having the toolchain do somewhat random optimizations will cause strange side-effects like "attempt to move .org backwards" compile-time errors. Already a simple "and" used in alternatives assembly will cause these mismatched code sizes. So prevent compressed instructions to be generated in alternatives- code and use option-push and -pop to only limit this to the relevant code blocks Signed-off-by: Heiko Stuebner <heiko@sntech.de> Reviewed-by: Christoph Hellwig <hch@lst.de> Reviewed-by: Philipp Tomsich <philipp.tomsich@vrull.eu> Link: https://lore.kernel.org/r/20220511192921.2223629-7-heiko@sntech.de Signed-off-by: Palmer Dabbelt <palmer@rivosinc.com>		2022-05-11 21:36:32 -07:00
