From 93d90f466b0a6faa6a7811187139f66a2b9c9c74 Mon Sep 17 00:00:00 2001 From: Alan Modra Date: Mon, 2 Aug 2010 13:19:44 +0000 Subject: PR gas/11867 * expr.c (operand <'-' and '~'>): Widen bignums. (operand <'!'>): Correct bignum result and convert to O_constant. * read.c (emit_expr): Don't assert on .byte bignum. Don't display bignum truncated warning for sign extended bignums. --- gas/expr.c | 21 ++++++++++++++------- 1 file changed, 14 insertions(+), 7 deletions(-) (limited to 'gas/expr.c') diff --git a/gas/expr.c b/gas/expr.c index a6910bf91ea..53952b56fa1 100644 --- a/gas/expr.c +++ b/gas/expr.c @@ -1056,6 +1056,15 @@ operand (expressionS *expressionP, enum expr_mode mode) { for (i = 0; i < expressionP->X_add_number; ++i) generic_bignum[i] = ~generic_bignum[i]; + + /* Extend the bignum to at least the size of .octa. */ + if (expressionP->X_add_number < SIZE_OF_LARGE_NUMBER) + { + expressionP->X_add_number = SIZE_OF_LARGE_NUMBER; + for (; i < expressionP->X_add_number; ++i) + generic_bignum[i] = ~(LITTLENUM_TYPE) 0; + } + if (c == '-') for (i = 0; i < expressionP->X_add_number; ++i) { @@ -1066,14 +1075,12 @@ operand (expressionS *expressionP, enum expr_mode mode) } else if (c == '!') { - int nonzero = 0; for (i = 0; i < expressionP->X_add_number; ++i) - { - if (generic_bignum[i]) - nonzero = 1; - generic_bignum[i] = 0; - } - generic_bignum[0] = nonzero; + if (generic_bignum[i] != 0) + break; + expressionP->X_add_number = i >= expressionP->X_add_number; + expressionP->X_op = O_constant; + expressionP->X_unsigned = 1; } } else if (expressionP->X_op != O_illegal -- cgit v1.2.3
