[Bug binutils/11436] New: c++filt does not support the C++0x lambdas of GCC 4.5

2010-03-27 Thread bruno at clisp dot org 
In version 2.20.1, c++filt does not know about the name mangling
of C++0x lambda expression types that GCC 4.5.0 snapshot 20100322
supports.

How to reproduce:
- Install GCC 4.5.0 from source in the SVN.
- Compile the attached program:
  $ g++ -O -S -std=c++0x lambda.cc
  $ c++filt < lambda.s | grep size

Result is:
.size   
_ZSt25__unguarded_linear_insertIPfZ7abssortS0_jEUlffE_EvT_T0_, 
.-_ZSt25__unguarded_linear_insertIPfZ7abssortS0_jEUlffE_EvT_T0_
.size

FWIW, it works on trunk:

void std::__unguarded_linear_insert(float*, abssort(float*, unsigned
int)::{lambda(float, float)#1}), .-void std::__unguarded_linear_insert(float*, abssort(float*,
unsigned int)::{lambda(float, float)#1})
.size
void std::__adjust_heap(float*, int, float*, float, abssort(float*,
unsigned int)::{lambda(float, float)#1}), .-void std::__adjust_heap(float*, int,
float*, float, abssort(float*, unsigned int)::{lambda(float, float)#1})
.size
void std::__introsort_loop(float*, abssort(float*, unsigned
int)::{lambda(float, float)#1}, int, abssort(float*, unsigned
int)::{lambda(float, float)#1}), .-void std::__introsort_loop(float*, abssort(float*,
unsigned int)::{lambda(float, float)#1}, int, abssort(float*, unsigned
int)::{lambda(float, float)#1})
.size
void std::__insertion_sort(float*, abssort(float*, unsigned int)::{lambda(float, float)#1},
