Does your _dl_tlsdesc_dynamic save ALL caller-saved registers, except for the return value register? I saw stp x5, x6, [sp, #16*1] stp x7, x8, [sp, #16*2] stp x9, x10, [sp, #16*3] stp x11, x12, [sp, #16*4] stp x13, x14, [sp, #16*5] stp x15, x16, [sp, #16*6] stp x17, x18, [sp, #16*7] Do you need to save x1 to x4? -- H.J. _______________________________________________ linaro-toolchain mailing list -- linaro-toolchain@lists.linaro.org To unsubscribe send an email to linaro-toolchain-le...@lists.linaro.org
