Bug ID: 12166
Summary: Compiling nodejs for SAMA5D3 always crash with illegal
instruction
Product: buildroot
Version: 2019.05.1
Hardware: Other
OS: Linux
Status: NEW
Severity: normal
Priority: P5
Component: Other
Assignee: unassigned at buildroot.uclibc.org
Reporter: marvin at mydatex.cz
CC: buildroot at uclibc.org
Target Milestone: ---
I compile buildroot with attached config for SAMA5D3 ARM CPU. When I enable
EABIHF and VFPv3-D16 (I test all combination of VFP) nodejs always crash with
illegal instruction. I test many combination of version buildroot but always
crash. But I found solution. When I compile nodejs ouside buidroot but using
buildroot toolchain. All works perfect. When I backtrace and disassemble code I
found
that nodejs crash here:
0x0073ddec <+160>: vldr d17, [r2]
If I understand this well that when I compile for VFPv3-D16 there should not be
register D17 used. This generate illegal instruction.
When I use this configure:
export CC=arm-buildroot-linux-uclibcgnueabihf-gcc
export CXX=arm-buildroot-linux-uclibcgnueabihf-g++
export CC_host="gcc -m32"
export CXX_host="g++ -m32"
/configure --prefix=../install --dest-cpu=arm --cross-compiling --dest-os=linux
--with-arm-float-abi=hard --with-arm-fpu=vfpv3-d16
I mean then inside buidroot is to configure passed wrong options
with-arm-fpu=vfpv3-d16.
Don't hestiate contact me.
