    • Add a contrib script for comparing the performance of two sets of · bff0e529 
      compiler runs.

Usage documentation is in the script.

The script produces output of the form:

$ compare_two_ftime_report_sets "Log0/*perf" "Log3/*perf" 

Arithmetic sample for timevar log files
"Log0/*perf"
and selecting lines containing "TOTAL" with desired confidence 95 is 
trial count is 4, mean is 443.022 (95% confidence in 440.234 to 445.811),
std.deviation is 1.75264, std.error is 0.876322

Arithmetic sample for timevar log files
"Log3/*perf"
and selecting lines containing "TOTAL" with desired confidence 95 is 
trial count is 4, mean is 441.302 (95% confidence in 436.671 to 445.934),
std.deviation is 2.91098, std.error is 1.45549

The first sample appears to be 0.39% larger,
with 60% confidence of being larger.
To reach 95% confidence, you need roughly 14 trials,
assuming the standard deviation is stable, which is iffy.

Tested on x86_64 builds.

    • Add a new option --clean_build to validate_failures.py · b436bf38 
      This is useful when you have two builds of the same compiler.  One with
your changes.  The other one, a clean build at the same revision.
Instead of using a manifest file, --clean_build will compare the
results it gather from the patched build against those it gathers from
the clean build.

Usage

$ cd /top/of/patched/gcc/bld
$ validate_failures.py --clean_build=clean/bld-gcc

    • This patch renames sbitmap iterators to unify them with the bitmap iterators. · d4ac4ce2 
      Remove the unused EXECUTE_IF_SET_IN_SBITMAP_REV, which has an unconventional
interface.

Rename the sbitmap_iter_* functions to match bitmap's bmp_iter_* functions.
Add an additional parameter to the initialization and next functions to
match the interface in bmp_iter_*.  This extra parameter is mostly hidden
by the use of the EXECUTE_IF macros.

Rename the EXECUTE_IF_SET_IN_SBITMAP macro to EXECUTE_IF_SET_IN_BITMAP.  Its
implementation is now identical to that in bitmap.h.  To prevent redefinition
errors, both definitions are now guarded by #ifndef.  An alternate strategy
is to simply include bitmap.h from sbitmap.h.  As this would increase build
time, I have elected to use the #ifndef version.  I do not have a strong
preference here.

The sbitmap_iterator type is still distinctly named because it is often
declared in contexts where the bitmap type is not obvious.  There are less
than 40 uses of this type, so the burden to modify it when changing bitmap
types is not large.

Tested on x86-64, config-list.mk testing.

	match bitmap iterator.  Update callers.

	(EXECUTE_IF_SET_IN_SBITMAP): Rename EXECUTE_IF_SET_IN_BITMAP and
	adjust to be identical to the definition in bitmap.h.  Conditionalize
	the definition based on not having been defined.  Update callers.
	* bitmap.h (EXECUTE_IF_SET_IN_BITMAP): Conditionalize the definition
