Bug ID: 126484
Summary: error: too few arguments to function ‘unsigned int
__builtin_mips_get_fcsr(void)`
Product: gcc
Version: 16.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: gcc-bugzilla at geoff dot wozniak.ca
Target Milestone: ---
Use of the builtin function __builtin_mips_get_fcsr with the C++ driver results
in the error that there are not enough arguments passed, but the function does
not take any arguments.
The builtin is documented here:
https://gcc.gnu.org/onlinedocs/gcc-16.1.0/gcc/Other-MIPS-Built-in-Functions.html
An example on Compiler Explorer: https://godbolt.org/z/joaeEMhvj
I have tried this on various builds of GCC and they all produce the same
result. Here is the oldest one I have, using a build from Codescape.
% cat t.cpp
unsigned int wrapper() {
return __builtin_mips_get_fcsr ();
}
% mips-img-elf-g++ --version
mips-img-elf-g++ (Codescape GNU Tools 2016.05-01 for MIPS IMG Bare Metal) 4.9.2
% mips-img-elf-g++ -mhard-float -c t.cpp
t.cpp: In function ‘unsigned int wrapper()’:
t.cpp:2:35: error: too few arguments to function ‘unsigned int
__builtin_mips_get_fcsr(void)’
return __builtin_mips_get_fcsr ();
