Hi Linaro Toolchain Group,
I am comparing execution time (run time) of sin() trigonometric function
between following glibc (including libm) libraries for aarch64 (juno cortex
a57) :
Linaro glibc 2.19, Linaro eglibc 2.19, eglibc 2.19 (from
http://www.eglibc.org/) and Linaro glibc 2.21.
My observation for execution time of sin():
with Linaro glibc 2.19 and eglibc 2.19 = 1m24.703s (approx)
whereas,
with Linaro eglibc 2.19 & Linaro glibc 2.21 = 0m25.243s (approx)
Has Linaro optimized the libm functions for aarch64 in Linaro eglibc 2.19 ?
If yes, please point me to relevant reference from where I can find more
information on them.
Since the eglibc development from version 2.19 has stopped, will Linaro
maintain its own development version of glibc ?
I am using below snippet code and linux 'time' command to calculate the
time.
void sin_func(void)
{
double incr = 0.732;
double result, count = 0.0;
printf("%s\n", __func__);
while (count < 105414350.0) {
result = sin(count);
count += incr;
}
}
Thanks.

o Upstream GCC (2/6)
* Back to ongoing patches
o Linaro GCC release (7/6)
* Reviewed FSF branch merge into 4.8/4.9 branches
* Reviewed patches for tcwg-realease script
* Sent a first batch of backports for 5.1
Still pending due to validation infra. issues
o Misc (1/6)

# Progress #
* TCWG-805, aarch64 native debugging multi-arch support. [5/10]
Patches (part1) are posted upstream for review, need to rewrite some
of them. The rest of them are OK and can be pushed in after 7.10
branch is created.
Watchpoint support in multi-arch debugging. Both kernel and GDB need
some fixes. Ongoing.
* Complete the document of aarch64 tracepoint work. [1/10]
* FSF GDB. [2/10]
Review intel mpx patch again, and read something on intel
mpx stuff.
# Plan #
* TCWG-805, update some patches in part 1 patch series, and continue
the multi-arch watchpoint work.
