Subject: [patch] entry-values: Fix for C++ across CUs
Hi,
I have found with C++ entry-values do not work much. This is a problem
primarily for 'this' being in $rdi clobbered very soon and having a function
with 'this=<optimized out>' is pretty useless for core crash analysis.
It happens if the call is across CUs, where GCC uses name reference:
<2><7c>: Abbrev Number: 6 (DW_TAG_GNU_call_site)
<7d> DW_AT_low_pc : 0x40049e
<85> DW_AT_abstract_origin: <0xa8>
<1><a8>: Abbrev Number: 10 (DW_TAG_subprogram)
<a9> DW_AT_external : 1
<a9> DW_AT_name : f
<ab> DW_AT_decl_file : 1
<ac> DW_AT_decl_line : 26
<ad> DW_AT_linkage_name: (indirect string, offset: 0x83): _Z1fi
<b1> DW_AT_declaration : 1
The testcase tests tail calls which is another (compared to unrecovered values
such as 'this') reproduction of the same problem:
Cannot find function "f(int)" for a call site target at 0x4004ae in main
#0 g (x=2) at gdb.arch/amd64-tailcall-cxx1.cc:23
#1 0x00000000004004ae in main () at gdb.arch/amd64-tailcall-cxx1.cc:31
->
#0 g (x=x@entry=2) at gdb.arch/amd64-tailcall-cxx1.cc:23
#1 0x00000000004005c8 in f (x=x@entry=1) at gdb.arch/amd64-tailcall-cxx2.cc:23
#2 0x00000000004004ae in main () at gdb.arch/amd64-tailcall-cxx1.cc:31
There are two different fixes below. The first one only always works but it
always uses the demangled name, which is not exact. The second fix provides
the mangled name (if available); the mangled name would not need the first fix
but the mangled name is sometimes not available - for example in Fedora GCC.
No regressions on {x86_64,x86_64-m32,i686}-fedora19pre-linux-gnu.
Probably nothing interesting, I will check it in.
Thanks,
Jan

Subject: [patch] entry-values: Fix if callee called noreturn function
Hi,
while debugging the previous bug I found this bug.
THIS_PC found below is then passed to get_pc_function_start.
get_pc_function_start cannot handle PC which has address of the end of the
function.
No regressions on {x86_64,x86_64-m32,i686}-fedora19pre-linux-gnu.
I will check it in.
Thanks,
Jan

Fix entry-values if the callee called a noreturn function.
* dwarf2-frame-tailcall.c (dwarf2_tailcall_sniffer_first): Use
get_frame_address_in_block. Add new comment.
