Bug ID: 30953 Summary: Objdump cuts 32bit displacements for AVX instructions Product: binutils Version: unspecified Status: NEW Severity: normal Priority: P2 Component: binutils Assignee: unassigned at sourceware dot org Reporter: blarsen at redhat dot com Target Milestone: --- Compiling the following program with gcc: int global = 1; int main() { asm("vmovd %0, %%xmm0": "=m"(global) : : "xmm0"); return 0; } And examining with objump -d, I get the following disassembly for the main function: 0000000000401106 <main>: 401106: 55 push %rbp 401107: 48 89 e5 mov %rsp,%rbp 40110a: c5 f9 6e 05 0a 2f 00 vmovd 0x2f0a(%rip),%xmm0 # 40401c <global> 401111: 00 401112: b8 00 00 00 00 mov $0x0,%eax 401117: 5d pop %rbp 401118: c3 ret notice how byte 401111 is a single null byte. That byte is part of the 32 bit displacement for the vmovd instruction, and should be printed in the same line.
