4Subject: [PATCH] avoid h asm constraint for MIPS
5
6The h asm constrain (to extract the high part of a multiplication
7result) has not been recognised since gcc 4.4:
8
9 https://gcc.gnu.org/gcc-4.4/changes.html
10
11Drop the MIPS umul_ppmm() implementations which rely on "=h" and fall
12back to the older implementations (which use explicit mfhi and mflo
13instructions to move the high and low parts of the multiplication
14result into their destinations).
15
16Upstream-Status: Inappropriate [upstream has a different solution]
