GCC testing questions

[Gary Funck]

Hello,

We're doing some work with an older 2.7.2 based GCC, targeting a MIPS
R3K. The client using the compiler asked how the compiler is tested,
and we noted that we had run version 1.44 of the c-torture tests
because those were the ones available at the time. The QA group wants
to know if that was the "correct" version of the test suite for the
version of GCC (2.7.2) and assembler being used. They'd also like to
know if the handful of failures encountered were the 'expected'
failures (we verified that the failures weren't important).

They'd basically like to know if there is a correspondence table
somewhere that shows which version of the C torture test was used to
"qualify" a given configuration of the GCC toolset. Also, is there any
documentation available as to the feature/bug that each C torture test
is intended to test? Would someone here please help fill me in on the
answers to those questions? Thanks.

Finally, when the base configuration of GCC is tested before being
'frozen' is there a minimum set of tests such as (1) C torture test,
(2) Perenial Test Suite (3) Linux builds on an x86 and doesn't exhibit
any compiler-related problems - that are must pass before a given
baseline is designated as stable, reliable, and ready for general use?
