2014-01-22Add ARI (ok) marker for __func__ reference in common-utils.hJoel Brobecker2-1/+6
The ARI script flagged the use of the __func__ variable, which is normally not allowed (not defined in C90). However, this particular use is OK, as the reference is only made when __STDC_VERSION__ >= 199901L. So, add an "ARI:" comment to explicitly OK this use. gdb/ChangeLog: * common/common-utils.h: Add "ARI:" comment beside __func__ reference.
2014-01-22Expand documentation of common-utils.h::FUNCTION_NAMEJoel Brobecker2-1/+11
While looking at this macro, I noticed that it wasn't always necessarily defined. That prompted me to search the current sources to make sure that all uses were adequately protected, which they were. But to help prevent future uses to be made unprotected, this patch expands the current macro documentation a bit. gdb/ChangeLog: * common/common-utils.h (FUNCTION_NAME): Expand the macro's documentation a bit.

2014-01-22Make assignments to dot keep an empty output section.Alan Modra19-38/+157
An assignment to dot in an output section that allocates space of course keeps the output section. Here, I'm changing the behaviour for assignments that don't allocate space. The idea is not so much to allow people to force output of an empty section with ". = .", but to fix cases where an otherwise empty section has padding added by an alignment expression that changes with relaxation or .eh_frame editing. Such a section might have zero size before relaxation and so be stripped incorrectly. ld/ * ld.texinfo (Output Section Discarding): Mention assigning to dot as a way of keeping otherwise empty sections. * ldexp.c (is_dot, is_value, is_sym_value, is_dot_ne_0, is_dot_plus_0, is_align_conditional): New predicates. (exp_fold_tree_1): Set SEC_KEEP when assigning to dot inside an output section, except for some special cases. * scripttempl/elfmicroblaze.sc: Use canonical form to align at end of .heap and .stack. ld/testsuite/ * ld-shared/elf-offset.ld: Align end of .bss with canonical form of ALIGN that allows an empty .bss to be removed. * ld-arm/arm-dyn.ld: Likewise. * ld-arm/arm-lib.ld: Likewise. * ld-elfvsb/elf-offset.ld: Likewise. * ld-mips-elf/mips-dyn.ld: Likewise. * ld-mips-elf/mips-lib.ld: Likewise. * ld-arm/arm-no-rel-plt.ld: Remove duplicate ALIGN. * ld-powerpc/vle-multiseg-1.ld: Remove ALIGN at start of section.

2014-01-21Check incompatible existing default symbol definitionH.J. Lu11-5/+106
After resolving a versioned reference, foo@VER1, to a default versioned definition, foo@@VER1, from a shared object, we also merge it with the existing regular default symbol definition, foo. When foo is IFUNC and foo@@VER1 aren't, we will merge 2 incompatible definitions. This patch avoids merging foo@@VER1 definition with foo definition if one is IFUNC and the other isn't.

2014-01-21Ensure that %func() expressions are outermost termsDJ Delorie2-1/+42
This is to avoid expressions like: %hi(foo) + 1, which will not do what you expect. The complex relocations can handle it, but the internal fixups can't.

2014-01-20gdb: xtensa: fix linux ptrace includesBaruch Siach4-1/+11
Currently, xtensa code using the Linux ptrace interface only include sys/ptrace.h. This file comes from the C library (glibc and uClibc, at least), and includes a declaration of the ptrace() functions, along with some cross architecture constants that are mostly copied from the file located at include/uapi/linux/ptrace.h in recent Linux kernels. For xtensa specific constants like PTRACE_GETXTREGS and PTRACE_SETXTREGS the asm/ptrace.h include from the Linux kernel UAPI is needed. The code in gdbserver xtensa specific part doesn't call ptrace() directly, so we can remove the unneeded sys/ptrace.h include. The gdb xtensa specific code needs both headers, since it calls ptrace(). gdb/ * xtensa-linux-nat.c: Include asm/ptrace.h. gdb/gdbserver/ * linux-xtensa-low.c: Include asm/ptrace.h instead of sys/ptrace.h.

The test fails on s390 with: -trace-find frame-number 0^M &"PC not available\n"^M ^done,found="1",tracepoint="1",traceframe="0",frame={level="-1",addr="<unavailable>",func="??",args=[]}^M (gdb) ^M FAIL: gdb.trace/mi-traceframe-changed.exp: tfile: -trace-find frame-number 0 tfile knows to infer the PC from the tracepoint's address if the PC wasn't collected (tfile_fetch_registers) but, that only works on targets whose PC register is a raw register, and on s390, the PC register is a pseudo register. But even if GDB doesn't know how to infer the value of PC, saying the current frame is level -1 is a bug: ^done,found="1",tracepoint="1",traceframe="0",frame={level="-1",addr="<unavailable>",func="??",args=[]}^M ^^^^^^^^^ '-1' is the level of the sentinel frame, which should never be visible. This is caused by the s390's heuristic unwinder accepting the frame (the fallback heuristic unwinders _always_ accept the frame), but then the unwind->this_id method throws that "PC not available\n" error. IOW, the s390's heuristic unwinder was never adjusted to handle unavailable register values gracefully, which can happen with e.g., a trimmed core file too. This is just the minimal necessary for <unavailable> frames, which at least gets us: (gdb) tfind Found trace frame 0, tracepoint 1 #0 <unavailable> in ?? () That is, frame #0 instead of -1.
