[LLVMdev] Measurements of the new inlinehint attribute
...r. It mostly affects the performance of -Os compiled code. I have made some measurements on the SPEC test suite to show what it means.
I made three runs of then nightly tests. The baseline represents -Os with no inlinehint:
make TEST=nightly OPTFLAGS=-Os EXTRA_LOPT_OPTIONS=-inlinehint-threshold=0 EXTRA_LINKTIME_OPT_FLAGS=-inlinehint-threshold=0 report
For the second run I enabled the inline hint, keeping the -Os flag:
make TEST=nightly OPTFLAGS=-Os report
The third run is -O3:
make TEST=nightly OPTFLAGS=-O3 EXTRA_LOPT_OPTIONS=-inline-threshold=275 EXTRA_LINKTIME_OPT_FLAGS=-inline-threshold=275 report

[LLVMdev] LLC fail without gccld optimization on spec2000 int benchmarks
Hi,
In my experiments, I need to disable several linking optimizations. However,
bzip2, vortex and eon failed if "-disable-opt" was passed to gccld. I tried
the out-of-box llvm and the building process provided by llvm-test. The same
problem was observed, when I specified EXTRA_LINKTIME_OPT_FLAGS =
-disable-opt on Makefile.program and simplied typed "make" under
llvm-test/External/SPEC/CINT2000. Seems that these errors come from llc
backend. But I have to stick to x86 backend because otherwise I can not
control the optimization passes that gcc will put on the generated c code.
I...
