Bug ID: 70894
Summary: ICE when using neon intrinsic with mabi=apcs-gnu
Product: gcc
Version: 5.3.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: g.hoogewerf at gmail dot com
Target Milestone: ---
The following test case triggers an ICE on several versions of GCC, including
5.3.0 and 4.9.3.
void crashFunction(unsigned char val)
{
__builtin_neon_vdup_nv16qi ((__builtin_neon_qi) val);
}
To trigger the ICE, the source should be compiled with:
arm-none-eabi-gcc -c neon.c -mfpu=neon -mfloat-abi=softfp -mabi=apcs-gnu
When running with -v -save-temps, the output is:
Using built-in specs.
