[PATCH 0/6] PR binutils/22875: More unsupported relocation handling target backend fixes

["Maciej W. Rozycki" <macro at mips dot com>]

Hi,

 In the course of adjusting the strip-13 test case for correct MIPS target 
coverage I have discovered further problems with unsupported relocation 
handling across a few target backends, including the MIPS backend itself. 
Here's a small patch series to address them.  No regressions across the 
usual targets.  See individual descriptions for details.

 A pattern repeats across a few targets, where out-of-bounds accesses are 
made to the respective howto tables for unsupported relocations, making 
behaviour unpredictable and possibly leading to a crash.  I have only 
adjusted those which actually triggered in my testing with strip-13 test 
case adjustments to come.  There may be more.

 Also the x86-64 backend seems to mishandle unsupported relocations that 
have the recently added (with commit 78984959cb38 ("x86-64: Add 
R_X86_64_converted_reloc_bit")) R_X86_64_converted_reloc_bit bit set.  I 
found a possible fix too complicated for me to afford the time required to 
sort it now, so I'm leaving it up to H.J. to address.  More details will 
follow with strip-13 test case updates.  NB `readelf -r' does not handle 
R_X86_64_converted_reloc_bit either and reports an unrecognized relocation 
instead.

 Adjustments to the strip-13 test case will follow.
