Like it or not, the large size of debug information is a serious

for many people.
Link times are hurt by large size of debugging information. I have
many many complaints from some users of the PS3 toolchain that link
times are huge and from my investigation, found the size of the
debugging info contributed to most (if not all) of the increased link
times.
I forgot to mention the increase in debugging information about
prologue and eplogue (made by RTH) between 4.0.2 and 4.1.1 made the
link time increase a huge amount.
It's worth noting that not all systems store debug information in
executables. On Mac OS 10.5, the linker leaves debug info in the .o
files instead of copying it into the executable. As such, size of
debug info doesn't significantly affect link-time or executable size
(but it can obviously affect time to launch the debugger). I'm sure
there are other systems that do similar things.
If debug info size and link time is really such a serious problem for
so many users, perhaps people developing the gnu toolchain should
investigate an extension like this.
