[Qemu-devel] [PATCH 0/2] tcg: Add tcg_gen_mulsu2_*

While reviewing the recent riscv patch set, I made a suggestion to copy some of the bits from tcg_gen_muls2_i64 in order to implement the mulhsu instruction. However, I noticed that the same operation is present in another target, so I thought that it would be better to have this as a standard

[Qemu-devel] [PATCH 2/2] target-microblaze: Cleanup dec_mul

Use tcg_gen_mul_tl for muli and mul instructions. Use tcg_gen_muls2_tl for mulh instruction. Use tcg_gen_mulu2_tl for mulhu instruction. Use tcg_gen_mulsu2_tl for mulhsu instruction. Note that this last fixes a bug, in that mulhsu was previously treating both operands as signed, instead of

[Qemu-devel] [PATCH 1/2] tcg: Add tcg_gen_mulsu2_{i32,i64,tl}

This multiply has one signed input and one unsigned input, producing the full double-width result. Signed-off-by: Richard Henderson --- tcg/tcg-op.c | 43 +++ tcg/tcg-op.h | 4 2 files changed, 47 insertions(+) diff --git

[Qemu-devel] [PATCH V9 0/7] coroutine: mmap stack memory and stack size

I decided to split this from the rest of the Qemu RSS usage series as it contains the more or less non contentious patches. I omitted the MAP_GROWSDOWN flag in mmap as we are not 100% sure which side effects it has. I kept the guard page which is now nicely makes the stacks visible in smaps. The

[Qemu-devel] [PATCH V9 7/7] coroutine: reduce stack size to 60kB

evaluation with the recently introduced maximum stack usage monitoring revealed that the actual used stack size was never above 4kB so allocating 1MB stack for each coroutine is a lot of wasted memory. So reduce the stack size to 60kB which should still give enough head room. The guard page added
