Description
test.c:
I compile test.c using "gcc -m32 -no-pie -fno-pic test.c -o gcc_32_O3 -O3". Function f is inlined in main. But I check by ida pro that function f still exists in gcc_32_O3 binary.
Then I lift gcc_32_O3 using "retdec-decompiler.py gcc_32_O3".
The output .ll doesn't have the ir of function f.
Was the way I lifted the gcc_32_O3 wrong? Or there is a bug?

Research direction
Reproduce the report from test.c using the stated gcc command, then run retdec-decompiler.py on gcc_32_O3 and compare the binary view in IDA Pro with the generated .ll output. Determine whether the invocation is incorrect or whether the lifted output loses the inlined function, and document a minimal reproducible diagnosis.
