This is a minor bugfix release, which to my knowledge contains nothing of importance to us. However, there is one QoL change to our patches. We no longer force `-fpic` in the compiler driver, and instead use the `--enable-default-pie` configure option to generate position-independent code suitable for executables. For building shared libraries, the `-fpic` flag must be specified explicitly.

Subject: [PATCH] i386: Disable math errno for SerenityOS
|
|
|
|
SerenityOS uses exceptions for math error handling, which allows the
|
|
compiler to do more optimizations on calls to math functions. This patch
|
|
has the effect of setting -fno-math-errno by default.
