fixed point compile on armv5te architecture
Trying to compile fixed point on armv5te architecture, using opus 1.3.1. I configure with:
CPPFLAGS="-D_FORTIFY_SOURCE=2" CFLAGS="-march=armv5te -O2 -pipe -fstack-protector-strong -fno-plt" CXXFLAGS="-march=armv5te -O2 -pipe -fstack-protector-strong -fno-plt" LDFLAGS="-Wl,-O1,--sort-common,--as-needed,-z,relro" ./configure --prefix=/usr --disable-static --enable-custom-modes --enable-fixed-point --disable-silent-rules
The make fails with:
gcc -DHAVE_CONFIG_H -I. -I./include -I./celt -I./silk -I./silk/float -I./silk/fixed -D_FORTIFY_SOURCE=2 -march=armv5te -O2 -pipe -fstack-protector-strong -fno-plt -fvisibility=hidden -W -Wall -Wextra -Wcast-align -Wnested-externs -Wshadow -Wstrict-prototypes -MT celt/kiss_fft.lo -MD -MP -MF celt/.deps/kiss_fft.Tpo -c celt/kiss_fft.c -fPIC -DPIC -o celt/.libs/kiss_fft.o
{standard input}: Assembler messages:
{standard input}:971: Error: first transfer register must be even -- `ldrd r9,r10,[r3,#-8]'
{standard input}:1148: Error: first transfer register must be even -- `ldrd r5,r6,[r1,fp]'So looks like some faulty machine code for the armv5te architecture. Haven't yet worked out where this machine code is generated ...
