The bits-extras package
Mostly wraps low-level bit operations provided by GCC builtins, which translate to specialized instructions where available.
Atomic operations include CAS (compare-and-swap), lock, fetch & add and similar primitives suitable for low-level shared-memory synchronization.
Primitives from the
Extras subpackage would be useful to have in the proper
Data.Bits package, although this would probably require broader support
across different compiler backends.
The C code dynamically links to
libgcc_s, which can cause problems in GHCi.
GHCi does not currently support sonames and tries to open
libgcc_s.so.1. A possible workaround for GHCi on a linux
ln -s /lib/libgcc_s.so.1 /lib/libgcc_s.so. Let me know about
any other solutions to this issue for GHCi. Regular GHC compilation uses the
system linker with soname support and does not run into this issue.
