This still breaks build. Please fix, something like ret = 0 when the variable is declared should be enough. /src/qemu/hw/puv3_gpio.c: In function 'puv3_gpio_read': /src/qemu/hw/puv3_gpio.c:48:5: error: 'ret' may be used uninitialized in this function [-Werror=maybe-uninitialized] /src/qemu/hw/puv3_pm.c: In function 'puv3_pm_read': /src/qemu/hw/puv3_pm.c:74:5: error: 'ret' may be used uninitialized in this function [-Werror=maybe-uninitialized] /src/qemu/hw/puv3_dma.c: In function 'puv3_dma_read': /src/qemu/hw/puv3_dma.c:44:5: error: 'ret' may be used uninitialized in this function [-Werror=maybe-uninitialized] I won't apply the patches until this is fixed. > > Thanks, > > Guan Xuetao > --- > > Andreas Färber (1): > target-unicore32: Drop UC32_CPUID macros > > Guan Xuetao (18): > unicore32-softmmu: Add unicore32-softmmu build support > unicore32-softmmu: Add coprocessor 0(sysctrl) and 1(ocd) instruction > support > unicore32-softmmu: Make UniCore32 cpuid & exceptions correct and > runable > unicore32-softmmu: Implement softmmu specific functions > unicore32-softmmu: Make sure that kernel can access user space > unicore32-softmmu: Add puv3 soc/board support > unicore32-softmmu: Add puv3 interrupt support > unicore32-softmmu: Add puv3 ostimer support > unicore32-softmmu: Add puv3 gpio support > unicore32-softmmu: Add puv3 pm support > unicore32-softmmu: Add puv3 dma support > unicore32-softmmu: Add ps2 support > unicore32-softmmu: Add maintainer information for UniCore32 machine > unicore32-softmmu: Add is_default setting for puv3 machine > unicore32: Split UniCore-F64 instruction helpers from helper.c > unicore32: Disintegrate cpu_dump_state_ucf64 function > unicore32: Close dump-option of cpu_dump_state_ucf64 function > unicore32-softmmu: Add a minimal curses screen support > > MAINTAINERS | 8 + > arch_init.c | 2 + > arch_init.h | 1 + > configure | 1 + > cpu-exec.c | 1 + > default-configs/unicore32-softmmu.mak | 4 + > hw/Makefile.objs | 7 + > hw/puv3.c | 131 +++++++++ > hw/puv3.h | 49 ++++ > hw/puv3_dma.c | 109 +++++++ > hw/puv3_gpio.c | 141 +++++++++ > hw/puv3_intc.c | 135 +++++++++ > hw/puv3_ost.c | 151 ++++++++++ > hw/puv3_pm.c | 149 ++++++++++ > hw/unicore32/Makefile.objs | 6 + > linux-user/main.c | 3 +- > target-unicore32/Makefile.objs | 4 +- > target-unicore32/cpu.c | 19 +- > target-unicore32/cpu.h | 18 +- > target-unicore32/helper.c | 511 > +++++++++++---------------------- > target-unicore32/helper.h | 17 +- > target-unicore32/machine.c | 23 ++ > target-unicore32/op_helper.c | 44 +++- > target-unicore32/softmmu.c | 267 +++++++++++++++++ > target-unicore32/translate.c | 159 +++++++++-- > target-unicore32/ucf64_helper.c | 345 ++++++++++++++++++++++ > 26 files changed, 1904 insertions(+), 401 deletions(-) > create mode 100644 default-configs/unicore32-softmmu.mak > create mode 100644 hw/puv3.c > create mode 100644 hw/puv3.h > create mode 100644 hw/puv3_dma.c > create mode 100644 hw/puv3_gpio.c > create mode 100644 hw/puv3_intc.c > create mode 100644 hw/puv3_ost.c > create mode 100644 hw/puv3_pm.c > create mode 100644 hw/unicore32/Makefile.objs > create mode 100644 target-unicore32/machine.c > create mode 100644 target-unicore32/softmmu.c > create mode 100644 target-unicore32/ucf64_helper.c >
