[gprofng] Parsing of function definitions fails

Hi,

Thanks for the hint. But the double-quotes do not really help.

Function without any template parameter work:

(gp-display-text) fsingle _IO_vfscanf
_IO_vfscanf
         Exclusive Total CPU Time: 13.199 ( 14.3%)
         Inclusive Total CPU Time: 20.424 ( 22.1%)
                             Size:  33367
                       PC Address: 6:0x0006b1f0
                      Source File: (unknown)
                      Object File: (unknown)
                      Load Object: /lib/x86_64-linux-gnu/libc-2.27.so
                     Mangled Name:
                          Aliases:

Functions with one template parameter work:

(gp-display-text) fsingle rho_calc<double>
void rho_calc<double>(long, double const*, double*) [clone ._omp_fn.8]
         Exclusive Total CPU Time:  1.001 (  1.1%)
         Inclusive Total CPU Time:  1.001 (  1.1%)
                             Size:    828
                       PC Address: 12:0x000064f0
                      Source File: cg-omp.cpp
                      Object File: test.6.er/archives/cg-omp_1X48lPAm9a2
                      Load Object: 
/home/hpc/unrz/unrz55/projects/PELS-Tutorial/CG/code/cg-omp
                     Mangled Name: _Z8rho_calcIdEvlPKT_PS0_._omp_fn.8
                          Aliases:

But function with multiple template parameters cause problems:

(gp-display-text) fsingle csr_spmv_kernel
Error: No function with given name `csr_spmv_kernel' found.
(gp-display-text) fsingle "csr_spmv_kernel<double, int>(long, long, int 
const*, int const*, double const*, double const*, double*)"
Error: No function with given name `csr_spmv_kernel<double, int>(long, 
long, int const*, int const*, double const*, double const*, double*)' found.
(gp-display-text) fsingle "csr_spmv_kernel<double,int>(long, long, int 
const*, int const*, double const*, double const*, double*)"
Error: No function with given name `csr_spmv_kernel<double,int>(long, 
long, int const*, int const*, double const*, double const*, double*)' found.
(gp-display-text) fsingle "csr_spmv_kernel<double,int>"
Error: No function with given name `csr_spmv_kernel<double,int>' found.

(gp-display-text) fsingle csr_spmv_kernel [N]
Error: Invalid number entered: [N]
Error: Invalid number entered: [N]
Error: No function with given name `csr_spmv_kernel' found.


I checked the documentation (gprofng/doc) and there the double-quotes 
are not mentioned.

Best,
Thomas
