- Subject: [PATCH] linux-user: Tag vsx with ieee128 fpbits
- In OE we need this for ppc64le usermode to work since we generate 128bit
- long doubles and glibc 2.34 is now checking for this in hwcaps at
- runtime and failing to run the binary if machine does not support 128bit
- IEEE fp
- Fixes
- Fatal glibc error: CPU lacks float128 support (POWER 9 or later required)
- Upstream-Status: Pending
- Signed-off-by: Khem Raj <raj.khem@gmail.com>
