I don't see any of those "a_*" names in the output of 'nm' or 'readelf -a' on musl-1.1.8/lib/libc.so.

Here's my configure command:

./configure --prefix=$(pwd).install --syslibdir=/usr/rx30/musl/lib/ CFLAGS=-O3 CC=gcc

Here's a sample of the make output:

gcc -std=c99 -nostdinc -ffreestanding -fexcess-precision=standard -frounding-math -D_XOPEN_SOURCE=700 -I./arch/i386 -I./src/internal -I./include š-pipe -fomit-frame-pointer -fno-unwind-tables -fno-asynchronous-unwind-tables -Wa,--noexecstack -march=i486 -mtune=generic -Werror=implicit-function-declaration -Werror=implicit-int -Werror=pointer-sign -Werror=pointer-arith -fno-stack-protector -O3 -c -o crt/crt1.o crt/i386/crt1.s

cp crt/crt1.o lib/crt1.o

cp crt/Scrt1.o lib/Scrt1.o

cp crt/crti.o lib/crti.o

That a_* functions appear in this profile implies they were not inlined, which
is quite strange.š Are you positive -O3 was used for your musl compile?š Can
you check the list of symbols in libc.so (e.g. using nm or `readelf -a`) to
double check?

Thanks.
