From 88535dda9050377cc52dfffa20664484b0bb9f7f Mon Sep 17 00:00:00 2001 From: Kevin Enderby Date: Tue, 7 May 2013 21:40:58 +0000 Subject: [PATCH] Fix a bug in the MC asm parser evaluating expressions. It was treating: A = 9 B = 3 * A - 2 * A + 1 as B = 3 * A - (2 * A + 1) rdar://13816516 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181366 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/MC/MCParser/AsmParser.cpp | 2 +- test/MC/AsmParser/exprs.s | 1 + 2 files changed, 2 insertions(+), 1 deletion(-) diff --git a/lib/MC/MCParser/AsmParser.cpp b/lib/MC/MCParser/AsmParser.cpp index 2368e9e86a1..edefdb4c364 100644 --- a/lib/MC/MCParser/AsmParser.cpp +++ b/lib/MC/MCParser/AsmParser.cpp @@ -1092,7 +1092,7 @@ bool AsmParser::ParseBinOpRHS(unsigned Precedence, const MCExpr *&Res, MCBinaryExpr::Opcode Dummy; unsigned NextTokPrec = getBinOpPrecedence(Lexer.getKind(), Dummy); if (TokPrec < NextTokPrec) { - if (ParseBinOpRHS(Precedence+1, RHS, EndLoc)) return true; + if (ParseBinOpRHS(TokPrec+1, RHS, EndLoc)) return true; } // Merge LHS and RHS according to operator. diff --git a/test/MC/AsmParser/exprs.s b/test/MC/AsmParser/exprs.s index df075f85ecf..a7e10020b67 100644 --- a/test/MC/AsmParser/exprs.s +++ b/test/MC/AsmParser/exprs.s @@ -45,6 +45,7 @@ k: check_expr 0 || 0, 0 check_expr 1 + 2 < 3 + 4, 1 check_expr 1 << 8 - 1, 128 + check_expr 3 * 9 - 2 * 9 + 1, 10 .set c, 10 check_expr c + 1, 11 -- 2.34.1
