[PATCH v2 0/4] MR10775: vbscript: Fix and expand test coverage for BSTR comparison. (alternate)
Alternate version of !10766 This replaces runtime VT_RESERVED tracking with compile-time is_literal_expr at the AST level: comparison opcodes (equal/nequal/gt/gteq/lt/lteq/case) carry a flag arg with bit 0 = left-literal, bit 1 = right-literal, and var_cmp dispatches on those flags. No runtime stripping, no OP_strip_reserved, and Const references stay non-literal because they're EXPR_MEMBER nodes even though the value is inlined. -- v2: vbscript: Match Windows BSTR-vs-numeric and BSTR-vs-Boolean comparison. https://gitlab.winehq.org/wine/wine/-/merge_requests/10775

From: Francis De Brabandere <francisdb@gmail.com> ByRef parameter holding a BSTR still coerces to numeric for comparison ("5" = 5 is True). For VT_UI1/VT_CY operands, Windows string-compares against CStr(numeric) rather than numeric-coercing, so non-numeric BSTRs return False with no error and relational operators use lex order. Hex ("&hff") and scientific ("1e2") BSTRs parse as numeric.

From: Francis De Brabandere <francisdb@gmail.com> The compiler tags each comparison operand at the source-AST level: a bare numeric literal (EXPR_INT / EXPR_DOUBLE / EXPR_DATE, parens transparent) sets a flag bit on the comparison opcode, and var_cmp dispatches on that flag so BSTR vs literal numeric goes through numeric coercion (error 13 on parse failure) while BSTR vs non-literal numeric uses string compare against CStr(numeric). VT_BOOL is handled in the same branch with hardcoded "True"/"False" since VarBstrFromBool yields "-1"/"0". Const references compile to an EXPR_MEMBER node, so they are correctly tagged non-literal even though the value is inlined at compile time. --- dlls/vbscript/compile.c | 49 ++++++++++++- dlls/vbscript/interp.c | 73 +++++++++++++++---- dlls/vbscript/tests/lang.vbs | 135 ++++++++++++++++++++--------------- dlls/vbscript/vbscript.h | 20 ++++-- 4 files changed, 196 insertions(+), 81 deletions(-) diff --git a/dlls/vbscript/compile.c b/dlls/vbscript/compile.c index 16e661c98ff..52a3609eb41 100644 --- a/dlls/vbscript/compile.c +++ b/dlls/vbscript/compile.c @@ -204,6 +204,19 @@ static HRESULT push_instr_addr(compile_ctx_t *ctx, vbsop_t op, unsigned arg) return S_OK; } +static HRESULT push_instr_addr_uint(compile_ctx_t *ctx, vbsop_t op, unsigned arg1, unsigned arg2) +{ + unsigned ret; + + ret = push_instr(ctx, op); + if(!ret) + return E_OUTOFMEMORY; + + instr_ptr(ctx, ret)->arg1.uint = arg1; + instr_ptr(ctx, ret)->arg2.uint = arg2; + return S_OK; +} + static HRESULT push_instr_str(compile_ctx_t *ctx, vbsop_t op, const WCHAR *arg) { unsigned instr; @@ -590,6 +603,28 @@ static HRESULT compile_unary_expression(compile_ctx_t *ctx, unary_expression_t * return push_instr(ctx, op) ?
