Subject: Division by zero on A53 which does not raise an exception
Date: Mon, 28 Nov 2022 21:37:09 -0700 [thread overview]
Message-ID: <4789825.31r3eYUQgx@thunderbird> (raw)
I am working on a project which is using an A53 core. The core does not
raise an exception if there is a division by zero (for either integer or
floating point division).
The designers chose to set status bits for the floating point case but not
raise an exception. With the integer division no status bits are set.
Does the GCC compilers or Binutils assembler and linker have a way to deal
with this issue on the ARM A53 processor?
For Linux, was special support added in the kernel to help Glibc with this
issue? If so, I will comb the linux source tree.
My project is using GCC 7.3.0
