Implement GHC.Environment.getFullArgs This returns all the arguments, including those normally eaten by the RTS (+RTS ... -RTS). This is mainly for ghc-inplace, where we need to pass /all/ the arguments on to the real ghc. e.g. ioref001(ghci) was failing because the +RTS -K32m -RTS wasn't getting passed on.

joinToTargets to emit fixup code even when movement graph contains cycles First, cycles can only start of with registers and their destination must involve a register location. This is because memory locations are allocated exclusively for a virtual register and hence can never cause a conflict in the assignment, hence need no fixup code. Therefore, we only have to deal with InReg -> InReg, or InReg -> InReg/InMem movements. The strategy is to take the first cycle element, which is guaranteed to start with a register, spill it to a fresh memory location, compute the fixup for the rest, and restore from the spill slot to its destinations. The "rest" will degenerate into an acyclic scc, so we do not need take care of the empty list case in CyclicScc. ***END OF DESCRIPTION*** Place the long patch description above the ***END OF DESCRIPTION*** marker. The first line of this file will be the patch name. This patch contains the following changes: M ./compiler/nativeGen/RegisterAlloc.hs -6 +27
