| 4 | Subject: [PATCH] linux-user: Tag vsx with ieee128 fpbits |
| 5 | |
| 6 | In OE we need this for ppc64le usermode to work since we generate 128bit |
| 7 | long doubles and glibc 2.34 is now checking for this in hwcaps at |
| 8 | runtime and failing to run the binary if machine does not support 128bit |
| 9 | IEEE fp |
| 10 | |
| 11 | Fixes |
| 12 | Fatal glibc error: CPU lacks float128 support (POWER 9 or later required) |
| 13 | |
| 14 | Upstream-Status: Pending |
