We encountered following gcc error when we tried to build ARM Compute Library:
-----
src/core/NEON/kernels/NEDirectConvolutionLayerKernel.cpp: In lambda function:
src/core/NEON/kernels/NEDirectConvolutionLayerKernel.cpp:712:32: internal compiler error: in gimplify_var_or_parm_decl, at gimplify.c:1801

This issue was fixed by following upstream commit:
- Bug 67244 - [5/6 Regression] internal compiler error: in gimplify_var_or_parm_decl, at gimplify.c:1801
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=67244
1. Configure a platform project with following options:
$WIND_BASE/wrlinux/configure --enable-reconfig --enable-board=mv-armada-38x --enable-kernel=standard --enable-rootfs=glibc-core+debug --enable-build=production --with-rcpl-version=0026
2. Add following lint to local.conf to change DEFAULTTUNE
DEFAULTTUNE = "armv7athf-neon"
3. Build the platform and export SDK
make && make export-sdk
4. Install SDK
5. Git clone ARM Compute Library:
git clone https://github.com/ARM-software/ComputeLibrary.git
6. Compile NEDirectConvolutionLayerKernel.cpp as follows (please replace --sysroot option to appropriate path)
cd ComputeLibrary
mkdir -p build/src/core/NEON/kernels
arm-wrs-linux-gnueabi-g++ -o build/src/core/NEON/kernels/NEDirectConvolutionLayerKernel.o -c -Wno-deprecated-declarations -Wall -DARCH_ARM -Wextra -Wno-unused-parameter -pedantic -Wdisabled-optimization -Wformat=2 -Winit-self -Wstrict-overflow=2 -Wswitch-default -fpermissive -std=gnu++11 -Wno-vla -Woverloaded-virtual -Wctor-dtor-privacy -Wsign-promo -Weffc++ -Wno-format-nonliteral -Wno-overlength-strings -Wno-strict-overflow -Wno-implicit-fallthrough -Wlogical-op -Wnoexcept -Wstrict-null-sentinel -march=armv7-a -mthumb -mfpu=neon -mfloat-abi=hard --sysroot=<path to sysroot> -Werror -O0 -g -gdwarf-2 -fstack-protector-strong -D_GLIBCXX_USE_NANOSLEEP -DARM_COMPUTE_CPP_SCHEDULER=1 -DARM_COMPUTE_DEBUG_ENABLED -DARM_COMPUTE_ASSERTS_ENABLED -DARM_COMPUTE_LOGGING_ENABLED -Iinclude -I. -Ibuild/build/src/core -Ibuild/src/core -Ibuild/arm_compute/core/NEON/kernels/winograd -Iarm_compute/core/NEON/kernels/winograd -Ibuild/arm_compute/core/NEON/kernels/assembly -Iarm_compute/core/NEON/kernels/assembly src/core/NEON/kernels/NEDirectConvolutionLayerKernel.cpp
