From: Arnd Bergmann <arnd@arndb.de> When building with CONFIG_LD_DEAD_CODE_DATA_ELIMINATION, I sometimes see an assertion ld.lld: error: Entry trampoline text too bigHeh, "too big" seems a weird report for having it discarded. :) Any idea on this Fangrui? ( I see this is https://github.com/ClangBuiltLinux/linux/issues/1311 )This diagnostic is from an ASSERT in arch/arm64/kernel/vmlinux.lds ASSERT((__entry_tramp_text_end - __entry_tramp_text_start) == (1 << 16), "Entry trampoline text too big")
Can we not change the ASSERT to be <= PAGE_SIZE instead? -- Catalin _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
