[MIPS32] Can't get printf to work with %f && %lld

[Xavier Guérin]

Hi list,

I'm currently working on a MIPS32 processor and it seems that I can't  
get printf to work with float, long long, double, and long double.
I'm using the 1.17 version of newlib, and I got the same behavior with  
the 1.16 version. Here are my configurations :

GCC 4.3.2 :

Configured with: configure --prefix=/Users/xguerin/Workspace/ 
Toolchains/mips-sls-dnaos.toolchain --target=mips-sls-dnaos --enable- 
multilib --enable-languages=c --with-newlib

The mips-sls-dnaos is the same configuration as mips-elf. It only  
enables the support of my OS. I'm using the following multilib  
configuration: msoft-float EL/EB.

Newlib 1.17.0 :

configure --prefix=/Users/xguerin/Workspace/Toolchains/mips-sls- 
dnaos.toolchain --enable-multilib --enable-newlib-io-long-long -- 
enable-newlib-io-long-double --enable-newlib-io-c99-formats --disable- 
newlib-may-supply-syscalls --disable-newlib-supplied-syscalls --enable- 
newlib-multithread

The mips-sls-dnaos target support my OS. Its files are place in the  
libc/sys directory. The ${newlib_cflags} only contains "-G0 - 
DHAVE_NANOSLEEP".

I regression-tested those types without printing them, and them seem  
to work fine. I think it's important to notice that the same printf()  
with the same newlib configuration is working perfectly on the ARM  
architecture.

Any insight ?

Thank you for your help,
Xavier
