Bug ID: 32534 Summary: [GAS] Intel Assembly Bugs (Mishandle Labels) Product: binutils Version: 2.38 Status: UNCONFIRMED Severity: normal Priority: P2 Component: gas Assignee: unassigned at sourceware dot org Reporter: witbring at gmail dot com Target Milestone: --- I am reporting GNU AS bug found during research. The tests were conducted using the latest version (binutils 2.38). The issue occurs in the same way with previous versions as well. When some register names are used in operands, GAS interprets them as actual registers. Notably, GAS allows the creation of these labels, which could potentially lead to problems. 1. Example Code ``` .intel_syntax noprefix .data RAX: RbX: Rcx: .long 0 .text test: mov edx, DWORD PTR [RAX] mov edx, DWORD PTR [RbX] mov edx, DWORD PTR [Rcx] call rsP rsP: ret ``` 2. Compilation Command ``` gcc -c test.c ``` 3. Compiled Binary Output ``` 0000000000000000 <test>: 0: 8b 10 mov edx,DWORD PTR [rax] 2: 8b 13 mov edx,DWORD PTR [rbx] 4: 8b 11 mov edx,DWORD PTR [rcx] 6: ff d4 call rsp 0000000000000008 <rsP>: 8: c3 ret ``` -- You are receiving this mail because: You are on the CC list for the bug.
