            Bug ID: 28231
           Summary: relocation truncated to fit: R_X86_64_32S against
                    `.text'
           Product: binutils
           Version: 2.37
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: ld
          Assignee: unassigned at sourceware dot org
          Reporter: manisandro at gmail dot com
  Target Milestone: ---

On a current Fedora Rawhide with 

mingw64-binutils-2.37-2.fc36.x86_64
mingw64-gcc-11.2.1-3.fc35.x86_64

The following

typedef struct __A {
} A;

int main(int argc, char** argv) {

    A a;

        __asm__ __volatile__ (
            "leaq       1f,             %%rax"          "\n\t"
            "1:"                                        "\t"
            :
            /* No outputs */
            :
            [a] "m"     (a)
            :
            "%rax"
        );

    return 1;
}


results in 

$ x86_64-w64-mingw32-gcc -o test test.c
/tmp/ccfMmoPi.o:test.c:(.text+0x18): relocation truncated to fit: R_X86_64_32S
against `.text'
collect2: error: ld returned 1 exit status

This is a reduced testcase from mingw-tk, which fails to build due to this. The
full code triggering this [1] asm block.

(Note: I don't know asm well enough to judge whether the asm code in the test
case is a valid test case, I just reduced the full code to the minimum lines
triggering the error. Filing this attemping to fix a FTBFS of mingw-tk)
