(Updated June 13, 2013, 4:24 a.m.) Review request for Default and Gabe Black. Description ------- Changeset 9760:f7df7b862186 --------------------------- x86: Add support for FLDENV & FNSTENV Diffs ----- src/arch/x86/isa/microasm.isa 9df73385c878 src/arch/x86/isa/insts/x87/control/save_and_restore_x87_environment.py 9df73385c878 src/arch/x86/isa/decoder/x87.isa 9df73385c878 Diff: http://reviews.gem5.org/r/1917/diff/ Testing (updated) ------- Quick regressions pass. Minor stat differences in full regressions (to be expected since some instructions aren't no-ops anymore). Solves a bug triggered by switching between a simulated CPU that tries to save the x87 state and a virtualized CPU that restores the state (which is completely bogus unless FNSTENV is implemented).
