Hi,
this is the build failure on Windows with binutils for which GNU as accepts
the --gdwarf-5 switch but GNU ld generates broken binaries with DWARF 5.
We already have the HAVE_LD_BROKEN_PE_DWARF5 kludge to disable DWARF 5 in this
case but it only tames the DWARF version in the compiler, so th

In addition to the obvious cut-n-pasto where *udivmodsi4_pow2_zext_2
never matches, limit the range of the immediate operand to prevent
out of range immediate operand of AND instruction.
Found by inspection, the patterns rarely match (if at all), since

Hi,
As subject, this patch uses a union instead of constructing a new opaque
vector structure for each of the vqtbl[234] Neon intrinsics in arm_neon.h.
This simplifies the header file and also improves code generation -

-fdirect-extern-access is the default. With -fno-direct-extern-access:
1. Always use GOT to access undefined data and function symbols,
including in PIE and non-PIE. These will avoid copy relocations
in executables. This is compatible with existing executables and
shared libraries.
2.
Changes in the v2 patch.
1. GNU_PROPERTY_1_NEEDED_INDIRECT_EXTERN_ACCESS support has been added to
GNU binutils 2.38. But the -z indirect-extern-access linker option is
only available for Linux/x86. However, the --max-cache-size=SIZE linker
option was also addded within a day. --max-cache-size=
Generate the marker for -fno-direct-extern-access to indicate that the
object file uses GOT to access all external symbols. Access to protected
symbols in the resulting shared library is treated as local, which requires
canonical function pointers and cannot be used with copy relocation.
