-    [ARM] Access FPSCR on vfpv2
-    
-    GDB can fetch or store FPSCR on vfpv3, which has 32 VFP registers, but
-    fail to do so on vfpv2, which has 16 VFP registers.  GDB code is incorrect
-    for vfpv2,
-    
-           else if (tdep->vfp_register_count > 0
-                   && regno >= ARM_D0_REGNUM
-                   && regno <= ARM_D0_REGNUM + tdep->vfp_register_count)
-    
-    while FPSCR register number is defined as ARM_D0_REGNUM + 32.
-    
-      ARM_D0_REGNUM,                /* VFP double-precision registers.  */
-      ARM_D31_REGNUM = ARM_D0_REGNUM + 31,
-      ARM_FPSCR_REGNUM,
-    
-    The code above uses "<=" rather than "<", in order to put FPSCR in the
-    range, but it is only correct when tdep->vfp_register_count is 32.  On
-    vpfv2, it is 16, and FPSCR is out of the range, so fetch_vfp_regs or
-    store_vfp_regs are not called.

-    This problem can be fixed by
-    
-     - either each prologue analyzer doesn't throw exception,
-     - or catch the exception thrown from gdbarch_skip_prologue,
-    
-    I choose the latter because the former needs to fix *every* prologue
-    analyzer to not throw exception.
-    
-    This error can be reproduced by changing reread.exp.  The test reread.exp
-    has already test that breakpoint can be reset correctly after the
-    executable is re-read.  This patch extends this test by compiling test c
-    file with and without -fPIE.
-    
-    (gdb) run ^M
-    The program being debugged has been started already.^M
-    Start it from the beginning? (y or n) y^M
-    x86_64/gdb/testsuite/outputs/gdb.base/reread/reread' has changed; re-reading symbols.
-    Error in re-setting breakpoint 1: Cannot access memory at address 0x555555554790^M
-    Error in re-setting breakpoint 2: Cannot access memory at address 0x555555554790^M
-    Starting program: /scratch/yao/gdb/build-git/x86_64/gdb/testsuite/outputs/gdb.base/reread/reread ^M
-    This is foo^M
-    [Inferior 1 (process 27720) exited normally]^M
-    (gdb) FAIL: gdb.base/reread.exp: opts= "-fPIE" "ldflags=-pie" : run to foo() second time (the program exited)
-    
-    This patch doesn't re-indent the code, to keep the patch simple.

-    PR breakpoints/21886: mem-break: Fix breakpoint insertion location
-    
-    Fix a commit cd6c3b4ffc4e ("New gdbarch methods breakpoint_kind_from_pc
-    and sw_breakpoint_from_kind") regression and restore the use of
-    `->placed_address' rather than `->reqstd_address' as the location for a
-    memory breakpoint to be inserted at.  Previously
-    `gdbarch_breakpoint_from_pc' was used that made that adjustment in
-    `default_memory_insert_breakpoint' from the preinitialized value,
-    however with the said commit that call is gone, so the passed
-    `->placed_address' has to be used for the initialization.
-    
-    The regression manifests itself as the inability to debug any MIPS/Linux
-    compressed ISA dynamic executable as GDB corrupts the dynamic loader
-    with one of its implicit breakpoints, causing the program to crash, as
-    seen for example with the `mips-linux-gnu' target, o32 ABI, MIPS16 code,
-    and the gdb.base/advance.exp test case:
-    
-    (gdb) continue
-    Continuing.
-    
-    Program received signal SIGBUS, Bus error.
-    _dl_debug_initialize (ldbase=0, ns=0) at dl-debug.c:51
-    51          r = &_r_debug;
-    (gdb) FAIL: gdb.base/advance.exp: Can't run to main

-            `->placed_address' rather than `->reqstd_address' for the
