--- Comment #11 from Tamar Christina <tnfchris at sourceware dot org> --- (In reply to rrorden from comment #8) > So the proposal is to add an aarch64 linker option that places stubs after > input sections that need them, just like aarch32, and I would need to > implement the -ffunction-sections behavior in our aot compiler so each > function (and they are relatively small) gets a unique section name. The A53 > erratum would not force every stub section to align to 4k, but that is a > worst-case scenario. If this is correct, I am okay with it. > Yup, that correct, On the long run -ffunction-section would give you other benefits like letting the linker remove unused functions so you would likely end up with a size gain here if you don't use all functions. They would be merged in the end anyway so there's no downside after linking. > How does the linker know it is targeting an A53 core? I see ld options > --fix-cortex-a53-835769, --fix-cortex-a53-843419. Do these need to be set > explicitly? Yup, you need to explicit give it the option, though certain toolchains like the GNU A released from Arm come with them on by default. -- You are receiving this mail because: You are on the CC list for the bug.
