This usually helps compiler to not use built-in optimizations for string functions and mem* functions unnecessarily, since OE's compiler is hosted for linux cross compile, this also means we instruct it rightly for building a baremetal application Refresh the patches to apply without fuzz Fixes linking errors e.g. platform/qemu/virt/lib/libplatsbi.a(sbi_string.o): in function `sbi_memset': | /mnt/b/yoe/build/tmp/work/riscv64-yoe-linux/opensbi/0.5-r0/git/lib/sbi/sbi_string.c:102: undefined reference to `memset' | collect2: error: ld returned 1 exit status (From OE-Core rev: f599b6c77f3585c8917f4d685689da4cc8a8bf04) Signed-off-by: Khem Raj <raj.khem@gmail.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
QEMU Emulation Targets ====================== To simplify development, the build system supports building images to work with the QEMU emulator in system emulation mode. Several architectures are currently supported in 32 and 64 bit variants: * ARM (qemuarm + qemuarm64) * x86 (qemux86 + qemux86-64) * PowerPC (qemuppc only) * MIPS (qemumips + qemumips64) Use of the QEMU images is covered in the Yocto Project Reference Manual. The appropriate MACHINE variable value corresponding to the target is given in brackets.
