Bug ID: 20423
Summary: Integrated arm assembler doesn't understand vuzpq.u16
Product: libraries
Version: trunk
Hardware: PC
OS: All
Status: NEW
Severity: normal
Priority: P
Component: Backend: ARM
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Classification: Unclassified
This works fine with gcc:
thakis@ubu:~$ arm-linux-gnueabihf-g++ -c test.cc -mfpu=neon
thakis@ubu:~$ cat test.cc
void foo() {
asm volatile ("vuzpq.u16 q0, q1\n\t" : : :);
}
But clang says:
thakis$ ~/src/llvm-build/bin/clang -target arm-linux-androideabi -c
-mfpu=neon test.cc
<inline asm>:1:2: error: invalid instruction
vuzpq.u16 q0, q1
^
1 error generated.
