Subject: [PATCH 4.19 0/6] fix warning and errors on arm built with clang
Date: Fri, 17 Dec 2021 15:41:13 +0100 [thread overview]
Message-ID: <20211217144119.2538175-1-anders.roxell@linaro.org> (raw)
Hi,
Can this patchset be applied to linux-4.19.y. I've tried to build an arm
kernel for these defconfigs:
mini2440_defconfig, mxs_defconfig, imx_v4_v5_defconfig,
integrator_defconfig, lpc32xx_defconfig, s3c2410_defconfig,
nhk8815_defconfig, imx_v6_v7_defconfig, at91_dt_defconfig,
shmobile_defconfig, omap1_defconfig, multi_v5_defconfig,
orion5x_defconfig, footbridge_defconfig, davinci_all_defconfig
Without this patchset these configs faild to build.
Also I fixed a few warnings.
There are still a few more warnings to fix.
But this is a start.
I built the kernel with tuxmake and this is the command:
tuxmake --runtime podman --target-arch arm --toolchain clang-nightly --kconfig tinyconfig LLVM=1 LLVM_IAS=0
Similar results with clang-13.
Patch "net: lan78xx: Avoid unnecessary self assignment" fixes:
drivers/net/usb/lan78xx.c:949:11: warning: explicitly assigning value of variable of type 'u32' (aka 'unsigned int') to itself [-Wself-assign]

1 warning generated.
Patch "ARM: 8805/2: remove unneeded naked function usage" fixes:
arch/arm/mm/copypage-v4wb.c:47:9: error: parameter references not allowed in naked functions

Patch "mwifiex: Remove unnecessary braces from HostCmd_SET_SEQ_NO_BSS_INFO" fixes:

Patch "Input: touchscreen - avoid bitwise vs logical OR warning" fixes:
drivers/input/touchscreen/of_touchscreen.c:80:17: warning: use of bitwise '|' with boolean operands [-Wbitwise-instead-of-logical]
data_present = touchscreen_get_prop_u32(dev, "touchscreen-size-x",
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Patch "ARM: 8788/1: ftrace: remove old mcount support" fixes:
arch/arm/kernel/entry-ftrace.S:56:2: error: Ftrace requires CONFIG_FRAME_POINTER=y with GCC older than 4.4.0.
#error Ftrace requires CONFIG_FRAME_POINTER=y with GCC older than 4.4.0.

Patch "ARM: 8800/1: use choice for kernel unwinders" fixes the build
error:
clang: error: unknown argument: '-mapcs'
clang: error: unknown argument: '-mno-sched-prolog'
Cheers,
Anders
