2.11.2 Adding top-level assembler statements ¶

In addition to creating extended asm instructions within a function, there is support for creating “top-level” assembler statements, outside of any function.

C Function: void gcc_jit_context_add_top_level_asm (gcc_jit_context *ctxt, gcc_jit_location *loc, const char *asm_stmts) ¶

Create a set of top-level asm statements, analogous to those created by GCC’s “basic” asm syntax in C at file scope.

For example, to create the equivalent of:

     asm ("\t.pushsection .text\n"
          "\t.globl add_asm\n"
          "\t.type add_asm, @function\n"
          "add_asm:\n"
          "\tmovq %rdi, %rax\n"
          "\tadd %rsi, %rax\n"
          "\tret\n"
          "\t.popsection\n");

the following API calls could be used:

  gcc_jit_context_add_top_level_asm (ctxt, NULL,
                                     "\t.pushsection .text\n"
                                     "\t.globl add_asm\n"
                                     "\t.type add_asm, @function\n"
                                     "add_asm:\n"
                                     "\tmovq %rdi, %rax\n"
                                     "\tadd %rsi, %rax\n"
                                     "\tret\n"
                                     "\t# some asm here\n"
                                     "\t.popsection\n");
