# Workaround incorrect constant folding of subnormals in javac when the FPU
|
|
# does not handle subnormal arithmetic, like on ARM in Flush-to-zero mode.
|
|
# These workarounds avoid underflow conditions during the bootstrap so the
|
|
# JDK can correctly build itself. Compiling or running programs other than
|
|
# openjdk itself on such hardware may still cause unexpected behaviour.
