linux-user: sparc: Remove unused struct 'target_mc_fq'

2024-06-30T16:51:44Z

This struct is unused since Peter's Commit b8ae597f0e6d ("linux-user/sparc: Fix errors in target_ucontext structures") However, hmm, I'm a bit confused since that commit modifies the structure and then removes it, was that intentional?

target/sparc: Split psr and xcc into components

2023-11-05T19:53:13Z

Step in removing CC_OP: change the representation of CC_OP_FLAGS. The 8 bits are distributed between 6 variables, which should make it easy to keep up to date. The code within cc_helper.c is quite ugly but is only temporary. Tested-by: Mark Cave-Ayland Acked-by: Mark Cave-Ayland Signed-off-by: Richard Henderson
