Bug #: 51372
Summary: internal compiler error: in write_builtin_type, at
cp/mangle.c:2204
Classification: Unclassified
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: carrot@google.com
Host: x86_64-build_unknown-linux-gnu
Target: arm-unknown-linux-gnueabi
Build: x86_64-build_unknown-linux-gnu
Compile the following source code with trunk g++ and options -march=armv7-a
-mfloat-abi=softfp -mfpu=neon -O2
#include <arm_neon.h>
void x(float32x4_t v0, float32_t f)
{
float32x4_t vv = vmulq_n_f32( v0, f);
}
GCC generates:
t0d2.ii:16:6: internal compiler error: in write_builtin_type, at
cp/mangle.c:2204
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.
The simplified preprocessed source code is:
-----------------------------------------------
typedef __builtin_neon_sf float32x4_t __attribute__ ((__vector_size__ (16)));
typedef __builtin_neon_sf float32_t;
__extension__ static __inline float32x4_t __attribute__ ((__always_inline__))
vmulq_n_f32 (float32x4_t __a, float32_t __b)
{
return (float32x4_t)__builtin_neon_vmul_nv4sf (__a, __b, 3);
}
void x(float32x4_t v0, float32_t f)
{
float32x4_t vv = vmulq_n_f32( v0, f);
}
------------------------------------------------
The complete command line is
cc1plus "-fpreprocessed" "t0d2.ii" "-quiet" "-dumpbase" "t0d.cpp"
"-march=armv7-a" "-mfloat-abi=softfp" "-mfpu=neon" "-auxbase-strip" "obj/t0d.o"
"-O2" "-o" "t0d.s"
This ICE is also existed in GCC 4.6.

__builtin_neon_sf is not really the float type.

> __builtin_neon_sf is not really the float type.
You are right. I mixed the new compiler with old arm_neon.h. In the new version
of arm_neon.h the definition of float32_t has been changed.
