x86-64: Align L(SP_RANGE)/L(SP_INF_0) to 8 bytes [BZ #21955]
sysdeps/x86_64/fpu/e_expf.S has lea L(SP_RANGE)(%rip), %rdx /* load over/underflow bound */ cmpl (%rdx,%rax,4), %ecx /* |x|<under/overflow bound ? */ ... /* Here if |x| is Inf */ lea L(SP_INF_0)(%rip), %rdx /* depending on sign of x: */ movss (%rdx,%rax,4), %xmm0 /* return zero or Inf */ ret ... .section .rodata.cst8,"aM",@progbits,8 ... .p2align 2 L(SP_RANGE): /* single precision overflow/underflow bounds */ .long 0x42b17217 /* if x>this bound, then result overflows */ .long 0x42cff1b4 /* if x<this bound, then result underflows */ .type L(SP_RANGE), @object ASM_SIZE_DIRECTIVE(L(SP_RANGE)) .p2align 2 L(SP_INF_0): .long 0x7f800000 /* single precision Inf */ .long 0 /* single precision zero */ .type L(SP_INF_0), @object ASM_SIZE_DIRECTIVE(L(SP_INF_0)) Since L(SP_RANGE) and L(SP_INF_0) are in .rodata.cst8 section, they must be aligned to 8 bytes. [BZ #21955] * sysdeps/x86_64/fpu/e_expf.S (L(SP_RANGE)): Aligned to 8 bytes. (L(SP_INF_0)): Likewise. (cherry picked from commit f59f7adb4a00b7784cab1becdf257366104587b7)
