Hello, I am trying to compile tcc on a little endian armv4 host simulated by
QEMU, the detailed info about this machine could be get from
http://people.debian.org/~aurel32/qemu/arm/
And I have 2 questions about it:
1. I can compile tcc with gcc, but failed with tcc it self
(--cc=/tcc/bin/tcc), how to fix it?
the error message is listed as follow:
debian-arm:~/tinycc# ./configure --prefix=/tcc --exec-prefix=/tcc
--cpu=armv4l --cc=/tcc/bin/tcc

2. I notice that the macro TCC_ARM_VFP is defined, but TCC_ARM_EABI is not,
what is the difference between arm-vfp-gcc and arm-eabi-tcc ? What to do
if I want arm-eabi-tcc ?
