--- Comment #2 from hjl at gcc dot gnu.org <hjl at gcc dot gnu.org> --- Author: hjl Date: Sun Mar 17 09:11:22 2019 New Revision: 269738 URL: https://gcc.gnu.org/viewcvs?rev=269738&root=gcc&view=rev Log: x32: Add addr32 prefix to VSIB address 32-bit indices in VSIB address are sign-extended to 64 bits. In x32, when 32-bit indices are used as addresses, like in vgatherdps %ymm7, 0(,%ymm9,1), %ymm6 32-bit indices, 0xf7fa3010, is sign-extended to 0xfffffffff7fa3010 which is invalid address. Add addr32 prefix to UNSPEC_VSIBADDR instructions for x32 if there is no base register nor symbol. This fixes 175.vpr and 254.gap in SPEC CPU 2000 on x32 with -Ofast -funroll-loops -march=haswell gcc/ Backport from mainline 2019-03-14 H.J.
