>Description:

I stumbled over some documentation glitches in the info-files:

Warning options:
"-Wall switches on a whole bunch of -W...-Options."
Unfortunately, the info-page only mentions this at
the end of the list. (At that point I already had hand-added all those
options, just to discard them again because this was redundant and
clobbered the cmd-line...)


"Options That Control Optimization"
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=
=3D=3D=3D=3D=3D=3D=3D=3D=3D

...
`-ftrapv'
     This option generates traps for signed overflow on addition,
     subtraction, multiplication operations.

Huh ?!
I guess this will make the program slower (because of the checks) but
better checked. So why is this listed under 'Optimization' ??
Shouldn't this be included under another section ??

"
`-ffunction-sections'
`-fdata-sections'
     Place each function or data item into its own section in the =
output
     file if the target supports arbitrary sections.  The name of the
     function or the name of the data item determines the section's =
name
     in the output file.

     Use these options on systems where the linker can perform
     optimizations to improve locality of reference in the instruction
     space.  HPPA processors running HP-UX and Sparc processors running
     Solaris 2 have linkers with such optimizations.  Other systems
     using the ELF object format as well as AIX may have these
     optimizations in the future.
"

I'm using gcc on HPUX 10.20 (HPPA)
Nevertheless I get:
cc1plus: warning: -ffunction-sections not supported for this target
cc1plus: warning: -fdata-sections not supported for this target
