Hi,
I'm experiencing troubles with va_list on the mips target. When one of the
parameter is either float (double), long long, or long double, and the function
handling the va_list is static inlined, the va_list argument is invalid.
The target triplet mips-sls-dnaos is an in-house description handling our OS
and equivalent to mips-elf.
The attached file is the .i of the regression application showing the buggy
behavior. The libC used is newlib 1.17.0.
FYI, the same application and the same compiler works fine on ARM targets.
