the just added new buildfarm member leveret (fedora core5 x86_64) is
building with the recently released Intel C-compiler version 9.1.
It passes all tests on -HEAD but fails on make check in both
REL8_1_STABLE and REL8_0_STABLE.
The logs of the later two branches also contain a very large number of
annoying(stupid) warnings - those seem to be the result of -HEAD using:
CFLAGS=-O2 -mp1 -fno-strict-aliasing -g
while the older branches have
CFLAGS=-O2 -Wall -Wmissing-prototypes -Wpointer-arith -Winline
-Wdeclaration-after-statement -Wendif-labels -fno-strict-aliasing -g
three things to note here:
*) why the large difference in the build-flags ?
*) the large amount of warnings are probably caused by -Wall
*) -HEAD has -mp1 which the intel compiler manual describes as:
-mp1 Improve floating-point precision. -mp1 disables fewer
optimizations and has less impact on performance than
-mp.
could that be the reason why -HEAD passes the float4/float8 regression
tests ?
