2014-08-18ada_evaluate_subexp<OP_VAR_VALUE>: Avoid static fixing when possible.Joel Brobecker2-2/+23
Now that the OP_VAR_VALUE section of this function has been reorganized a bit, we can fall-back on standard evaluation when static fixing is not required. This patch does that, but being exclusive about when static fixing has to be used, rather than doing it all the time when noside is EVAL_AVOID_SIDE_EFFECTS. This will pave the way for later when we want to evaluate entities that have no GNAT encodings related to them but dynamic properties instead. In that case, we expect the standard evaluation to resolve those dynamic properties for us, even in no-side-effect mode. gdb/ChangeLog: * ada-lang.c (ada_evaluate_subexp) <OP_VAR_VALUE>: When noside is EVAL_AVOID_SIDE_EFFECTS, only return a statically fixed value for records and unions for which some GNAT encodings are present.
2014-08-18avoid "if ... else if ... else" logic in ada-lang.c::ada_evaluate_subexpJoel Brobecker2-7/+13
The OP_VAR_VALUE branch in ada_evaluate_subexp is written with multiple "if ... else if ... else if ... else ..." block. But in practice, these blocks all either goto out of that block of code, or return. This patch rewrites this code slightly by replacing the "else if"-s by simple "if"s. This should better reflect the ideal processing where we try to do a standard eval whenever possible, and only do something else when the standard eval does not work. On a pratical level, this patch makes it easier to fall through to the default processing when none of the special situations are detected, thus making it easier to add more handlers of those special situations; or to remove them as they no longer become necessary! gdb/ChangeLog: * ada-lang.c (ada_evaluate_subexp) <OP_VAR_VALUE>: Slight code rewrite to avoid "else if" and "else" constructs. Should be a no-op in practice.
2014-08-18Fix indentation level in ada-lang.c::ada_evaluate_subexp.Joel Brobecker2-44/+49

2014-08-18PowerPC fix for ifunc broken by d1eca1e4Alan Modra3-1/+11

2014-08-15Set print symbol off in some testsYao Qi5-1/+17
GDB in default prints the symbol associated on an address, and tests assume that there is no symbol on address zero. However, on bare metal target, address may be mapped to zero and there may be a symbol. Then, some tests fail as below: print const_cast<void *> (0)^M $8 = (void *) 0x0 <_ftext>^M (gdb) FAIL: gdb.cp/casts.exp: const_cast of 0 p acp->c1^M $9 = (A *) 0x0 <_ftext>^M (gdb) FAIL: gdb.cp/class2.exp: p acp->c1 This patch is to set print symbol off in these tests, like what I did previously https://sourceware.org/ml/gdb-patches/2014-07/msg00257.html gdb/testsuite: 2014-08-15 Yao Qi <yao@codesourcery.com> * gdb.cp/casts.exp: Set print symbol off. * gdb.cp/class2.exp: Likewise. * gdb.cp/overload.exp: Likewise. * gdb.cp/templates.exp: Likewise.

2014-08-14configury changes to make ld plugin support controlled by --enable-pluginsAlan Modra21-1647/+1768
This also makes --enable-plugins default to on for hosts that can support plugins, so we have consistent lto toolchain support. The ACX_LARGEFILE moves aren't strictly necessary, but are harmless and will be necessary if plugin support is extended to more hosts via libtool's dlopen support. I started down that path then decided it was more work than I was interested in doing. (ACX_LARGEFILE invokes AC_PLUGINS.) config/ * plugins.m4: Test for dlfcn.h or windows.h here to set default for --enable-plugins. Report error if someone tries to enable plugins on a host we don't support. bfd/ * configure.ac: Delete redundant plugin related checks. * configure: Regenerate. binutils/ * configure.ac: Move ACX_LARGEFILE after LT_INIT. * config.in: Regenerate. * configure: Regenerate. gas/ * configure.ac: Move ACX_LARGEFILE after LT_INIT. * config.in: Regenerate. * configure: Regenerate. gprof/ * configure.ac: Move ACX_LARGEFILE after LT_INIT. * configure: Regenerate. * gconfig.in: Regenerate. ld/ * configure.ac: Move AC_PROG_CC and other macros earlier.

If the user gives us an unaligned PC, then dump an error as such. Otherwise if you try to disassemble at an odd address, the output will look weird (it'll read one byte earlier).

The main aim of this change was to have non_ir_ref set correctly on new indirect symbols.
