I tried to emerge Chromium on my arm64 gentoo, but it failed.
With the log file, I guess it's a bug.
build.log(only important part):

And, definition of | Code: | | vcvt_f16_f32 (float32x4_t __a) |
in arm_neon.h:
| Code: | __extension__ extern __inline float32x4_t
__attribute__ ((__always_inline__, __gnu_inline__, __artificial__))
vcvt_f32_f16 (float16x4_t __a)
{
return __builtin_aarch64_float_extend_lo_v4sf (__a);
} |
As I found on the Internet, this function is used to convert a vector with 4 16 bits float variable to a vector with 4 32 bits float variable. I don't understand why chromium use it to convert a int variable. |

https://bugs.chromium.org/p/chromium/issues/detail?id=818328
not sure if this is related, it failed in the same spot but im pretty sure the cause isn't the same as yours. they (that guy) was building with clang
more stuff https://bugs.llvm.org/show_bug.cgi?id=36582 | Code: | fix PR36582
The error occurs when reading i16 elements (as in the testcase) from a v8i8
with a pattern of <0,2,4,6>. As all the data in the vector is accessed, the
operation is not a VUZP. The patch stops the pattern recognition of VUZP when
EXTRACT_VECTOR_ELT has a different element type than BUILD_VECTOR. |

Moved from Portage & Programming to Gentoo on ARM.
