generated the gmon data. The support is currently limited to what is
easy to implement and/or needed:
signedess: signed or insigned
size: 8, 16, 32 or 64 bits
format: a binary integer in gprof's format (gprof is not a cross-tool).
High-resolution kernel profiling uses signed 64-bit counters. Normal
kernel profiling and user profiling use unsigned 16-bit counters but
should use 32-bit ones.
