Summary: [Bug] internal labels present in risc-v
Product: binutils
Version: 2.42
Status: NEW
Severity: enhancement
Priority: P2
Component: binutils
Assignee: unassigned at sourceware dot org
Reporter: akhilesh.k at samsung dot com
Target Milestone: ---
Hi All
`.LFB`, `.LVL`, `.LBB`, and `.LBE` are internal labels is expected in compiler
generated asm file since these are internal labels i was expecting not be
present in objdump.
using open source risc-v toolchain observed internal labels are visible in
objdump.
Is this related with architecture, compiler settings ?
because same settings i using for arm and riscv for arm these are not visible
but riscv these visible
