The sparc frontend is now the only user of the obsolete gen_io_end() function (used for icount support). This patchset removes the use from sparc as well, and then tidies up the generic icount infrastructure to remove the function altogether.
This is for-6.2 material because it's just cleanup. There is a slight difficulty here with testing this: icount doesn't seem to work for sparc Linux guests in master at the moment. For instance if you get the advent calendar image from https://www.qemu-advent-calendar.org/2018/download/day11.tar.xz it will boot without icount with a command line like qemu-system-sparc -display none -vga none -machine SS-20 -serial stdio -kernel /tmp/day11/zImage.elf But if you add '-icount auto' it will get as far as "bootconsole [earlyprom0] disabled" and then apparently hang. I'm not sure what's going on here :-( (I filed this as https://gitlab.com/qemu-project/qemu/-/issues/499) Anyway, these patches don't make the situation any worse... -- PMM Peter Maydell (2): target/sparc: Drop use of gen_io_end() tcg: Drop gen_io_end() docs/devel/tcg-icount.rst | 3 --- include/exec/gen-icount.h | 27 ++++++++++----------------- target/sparc/translate.c | 25 ++++++++++--------------- 3 files changed, 20 insertions(+), 35 deletions(-) -- 2.20.1
