Why does `-fno-plt` not work when compiling/linking assembly?

Question

I am interested in compiling / linking an assembly project whose shared library function calls bypass the PLT (use the GOT directly). I Tried using -fno-plt but the resulting library calls still go through the PLT.

Questions

I am wondering:

1. Why does the -fno-plt argument not work when compiling assembly?
2. Is there a way to compile assembly so that shared library function calls bypass the PLT?

Assembly PLT Bypass with -fno-plt NOT Working.

Using the simplest example:

    .global main
    .text
main:
    callq   exit

When compiled with:

gcc -fno-plt test0.S -o test0

Produces the following for main:

0000000000001139 <main>:
    1139:   e8 f2 fe ff ff          callq  1030 <exit@plt>
    113e:   66 90                   xchg   %ax,%ax

Which is calling exit through the PLT.

C PLT Bypass with -fno-plt Working

Alternatively the same code in C:

extern void exit(int);
int main() {
    exit(0);
}

Compiled with:

gcc -O2 -fno-plt  test1.c -o test1 

Gets the following for main:

0000000000001040 <main>:
    1040:   f3 0f 1e fa             endbr64 
    1044:   50                      push   %rax
    1045:   58                      pop    %rax
    1046:   31 ff                   xor    %edi,%edi
    1048:   48 83 ec 08             sub    $0x8,%rsp
    104c:   ff 15 96 2f 00 00       callq  *0x2f96(%rip)        # 3fe8 <exit@GLIBC_2.2.5>
    1052:   66 2e 0f 1f 84 00 00    nopw   %cs:0x0(%rax,%rax,1)
    1059:   00 00 00 
    105c:   0f 1f 40 00             nopl   0x0(%rax)

Which correctly bypasses the PLT for the call to exit.
