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.

--- Comment #2 from Thomas Petazzoni <[email protected]> --- It seems like the nodejs build system is overriding the mfpu flag, and OpenEmbedded has a patch to remove this logic, see
https://github.com/openembedded/meta-openembedded/blob/master/meta-oe/recipes-devtools/nodejs/nodejs/0007-v8-don-t-override-ARM-CFLAGS.patch.
Could you try to apply this patch to nodejs, and see if it fixes the issue for you ?
