"If the instruction executed immediately before an FBfcc is an FPop2

gdb/riscv: remove extra caching of misa register

The RISC-V had a mechanism in place to cache the contents of the misa
register per-inferior, the original intention behind this was to
reduce the number of times the misa register had to be read (as the
contents should be constant), but it was pointed out on the mailing
list[1] that the register cache will mean the register is only
accessed once each time GDB stops, and any additional caching is
probably just unneeded extra complexity.

As such, until it can be shown that there's a real need for additional
caching, this commit removes all of the additional caching of the misa
register, and just accesses the misa register like a normal register.

6 years agogdb: Ensure compiler doesn't optimise variable out in test
Andrew Burgess [Wed, 29 Aug 2018 17:49:51 +0000 (18:49 +0100)]
gdb: Ensure compiler doesn't optimise variable out in test

In the test gdb.base/funcargs.exp, there's this function:

    void recurse (SVAL a, int depth)
    {
      a.s = a.i = a.l = --depth;
      if (depth == 0)
        hitbottom ();
      else
        recurse (a, depth);
    }

The test script places a breakpoint in hitbottom, and runs the
executable which calls recurse with an initial depth of 4.

When GDB hits the breakpoint in hitbottom the testscript performs a
backtrace, and examines 'a' at each level.

The problem is that 'a' is not live after either the call to
'hitbottom' or the call to 'recurse', and as a result the test fails.

In the particular case I was looking at GCC for RISC-V 32-bit, the
variable 'a' is on the stack and GCC selects the register $ra (the
return address register) to hold the pointer to 'a'.  This is fine,
because, by the time the $ra register is needed to hold a return
address (calling hitbottom or recurse) then 'a' is dead.

In this patch I propose that a use of 'a' is added after the calls to
hitbottom and recurse, this should cause the compiler to keep 'a'
around, which should ensure GDB can find it.

* gdb.base/funcargs.c (use_a): New function.

Keith Seitz [Wed, 29 Aug 2018 22:12:24 +0000 (15:12 -0700)]
C++ compile support

This patch adds *basic* support for C++ to the compile feature.  It does
most simple type conversions, including everything that C compile does and
your basic "with-classes" type of C++.

I've written a new compile-support.exp support file which adds a new test
facility for automating and simplifying "compile print" vs "compile code"
testing.  See testsuite/lib/compile-support.exp and CompileExpression
for more on that.  The tests use this facility extensively.

This initial support has several glaring omissions:
- No template support at all
  I have follow-on patches for this, but they add much complexity
  to this "basic" support.  Consequently, they will be submitted separately.
- Cannot print functions
  The code template needs tweaking, and I simply haven't gotten to it yet.
- So-called "special function" support is not included
  Using constructors, destructors, operators, etc will not work. I have
  follow-on patches for that, but they require some work because of the
  recent churn in symbol searching.
- There are several test suite references to "compile/1234" bugs.
  I will file bugs and update the test suite's bug references before pushing
  these patches.

The test suite started as a copy of the original C-language support, but
I have written tests to exercise the basic functionality of the plug-in.

I've added a new option for outputting debug messages for C++ type-conversion
("debug compile-cplus-types").

also fixes (at least) one bug reported against GDB:

deciding whether to use the system's 'getcwd' or gnulib's version is
too simplistic and pessimistic, so when cross-compiling we always end
up using gnulib's version, which has a limitation: it cannot handle
the situation when the parent directory doesn't have read permissions.

This has been reported against upstream gnulib and the fix has been

This was because with frame filters enabled, the actual frame printing is
done in "py_print_frame" rather than "print_frame". This issue is now fixed.
