[LLVMdev] Floating point comparison doubt
Hi,
In unordered floating point comparison before making a call for
comparison proper one node called UO_F32 is generated. In targets this
node is replaced with a call to __unordsf2.
My doubts here
1) What are these UO_F32 and O_F32 nodes for?
2) What is this function (__unordsf2) supposed to do?
Regards
Sachin

[LLVMdev] RTLIB::UO_F32
what C code would produce the following when soft float is enabled?
(RTLIB::UO_F32, "__unordsf2");
(RTLIB::UO_F64, "__unorddf2");
(RTLIB::O_F32, "__unordsf2");
(RTLIB::O_F64, "__unorddf2");
tia.

[LLVMdev] RTLIB::UO_F32
Hi Reed,
Sorry about the off-list reply. I need to reset my list preferences.
If I build:
cmp.c:
int cmp_single(float a) { return (a != a) ? 1 : 0; }
int cmp_double(double a) { return (a != a) ? 1 : 0; }
with clang -target mips-unknown -S cmp.c
I get calls to __unordsf2 and __unorddf2.

Compiling for baremetal ARMv4 on Ubuntu Linux
I am currently trying to compile a pretty simple program to work on an
experimental board. It contains an (FPGA-version of) an ARMv4 processor.
So basically, I try this (on my Ubuntu 18.04.1 LTS):
clang -v --target=arm-none-eabi -c barehello.c -o barehelloCLANG.o
clang -v --target=arm-none-eabi -c io.c -o io.o
clang -v --target=arm-none-eabi barehelloCLANG.o io.o -o
helloCLANGstatic -static
