[Qemu-devel] trigonometric functions in softfloat

Hi, Thomas has pointed out that WinUAE[1] has an updated softfloat library implementing missing operations for 680x0. Do you think these changes can be merged in QEMU? Thanks, Laurent [1] https://github.com/tonioni/WinUAE/tree/master/softfloat

[Qemu-devel] [PATCH v2 0/4] migration: fix iotest 055, only-migratable break

v2: - patch 1: add r-b for Eduardo/Juan - patch 2: add r-b for Eduardo (Markus's suggestion is a todo), and t-b for Qingfeng - patch 3: rewrite the doc up, merging both Eduardo/Markus's suggestion [Eduardo, Markus] - patch 4: added a TODO [Markus] Two breakage introduced during the migration
