Error while building Arm clang tool chain

[rajathpd]

Hello,

We have followed these steps below to build arm clang tool chain:

-export ARMLMD_LICENSE_FILE=8224@xsjlicsrvip -export ARM_TOOL_VARIANT=ult -export PATH=/tools/installs/arm/safety/armcc/6.6.2/bin:$PATH -export ARM_INCLUDE=/tools/installs/arm/safety/armcc/6.6.2/include -export XTOOLS_VER=2023 -export CROSS_COMPILE=/proj/xbuilds/2023.1_daily_latest/installs/lin64/Vitis/2023.1/gnu/aarch64/lin/aarch64---linux/bin/aarch64-linux-gnu- -export PATH=/tools/installs/arm/safety/armcc/6.6.2/bin:$PATH -export ARM_INCLUDE=/tools/installs/arm/safety/armcc/6.6.2/include -make CC=/tools/installs/arm/safety/armcc/6.6.2/bin/armclang distclean -make -j4 CC=/tools/installs/arm/safety/armcc/6.6.2/bin/armclang RESET_TO_BL31=1 PLAT=zynqmp bl31

1) For this, we get an error in mbranch-protection flag in plat/xilinx/zynqmp/platform.mk saying: unknown argument: 'mbranch-protection=none'. I've attached a snippet for the same.

Resolution: In order to solve the above error, we commented -> TF_CFLAGS_aarch64 += -mbranch-protection=none By doing so we could resolve this error. Is it a right way to solve the error?

2) We get another error in include/arch/aarch64/smccc_helpers.h:114:23: error: expected expression smc_args_t ret_args ={0}; I've attached a snippet for the same.

Resolution: In order to solve this error, we removed the initialization: smc_args_t ret_args ={ }; Is it a right way to solve the error?

3) We get another error in lib/compiler-rt/builtins/int_lib.h :70:2: error: Unsupported target

error Unsupported target

Resolution: To solve the error, we defined: defined(clang) in int_lib.h Is it a right way to solve the error? Please suggest.

Thanks & regards, Rajath P D

Hi @rajathpd, could you try with the latest version of the integration branch? We have merged some changes that I suspect might already resolve this.

Hi @CJKay ,

I tried building the armclang by checking out to the integration branch but still got the same error. Please find the attached snippet of the error.

What version of Arm Clang are you using?
