From 0b57cec536236d46e3dba9bd041533462f33dbb7 Mon Sep 17 00:00:00 2001 From: Dimitry Andric Date: Fri, 20 Dec 2019 19:53:05 +0000 Subject: Move all sources from the llvm project into contrib/llvm-project. This uses the new layout of the upstream repository, which was recently migrated to GitHub, and converted into a "monorepo". That is, most of the earlier separate sub-projects with their own branches and tags were consolidated into one top-level directory, and are now branched and tagged together. Updating the vendor area to match this layout is next. --- .../lldb/source/Host/common/StringConvert.cpp | 95 ++++++++++++++++++++++ 1 file changed, 95 insertions(+) create mode 100644 contrib/llvm-project/lldb/source/Host/common/StringConvert.cpp (limited to 'contrib/llvm-project/lldb/source/Host/common/StringConvert.cpp') diff --git a/contrib/llvm-project/lldb/source/Host/common/StringConvert.cpp b/contrib/llvm-project/lldb/source/Host/common/StringConvert.cpp new file mode 100644 index 000000000000..8bf04f0a9ca3 --- /dev/null +++ b/contrib/llvm-project/lldb/source/Host/common/StringConvert.cpp @@ -0,0 +1,95 @@ +//===-- StringConvert.cpp ---------------------------------------*- C++ -*-===// +// +// Part of the LLVM Project, under the Apache License v2.0 with LLVM Exceptions. +// See https://llvm.org/LICENSE.txt for license information. +// SPDX-License-Identifier: Apache-2.0 WITH LLVM-exception +// +//===----------------------------------------------------------------------===// + +#include + +#include "lldb/Host/StringConvert.h" + +namespace lldb_private { +namespace StringConvert { + +int32_t ToSInt32(const char *s, int32_t fail_value, int base, + bool *success_ptr) { + if (s && s[0]) { + char *end = nullptr; + const long sval = ::strtol(s, &end, base); + if (*end == '\0') { + if (success_ptr) + *success_ptr = ((sval <= INT32_MAX) && (sval >= INT32_MIN)); + return (int32_t)sval; // All characters were used, return the result + } + } + if (success_ptr) + *success_ptr = false; + return fail_value; +} + +uint32_t ToUInt32(const char *s, uint32_t fail_value, int base, + bool *success_ptr) { + if (s && s[0]) { + char *end = nullptr; + const unsigned long uval = ::strtoul(s, &end, base); + if (*end == '\0') { + if (success_ptr) + *success_ptr = (uval <= UINT32_MAX); + return (uint32_t)uval; // All characters were used, return the result + } + } + if (success_ptr) + *success_ptr = false; + return fail_value; +} + +int64_t ToSInt64(const char *s, int64_t fail_value, int base, + bool *success_ptr) { + if (s && s[0]) { + char *end = nullptr; + int64_t uval = ::strtoll(s, &end, base); + if (*end == '\0') { + if (success_ptr) + *success_ptr = true; + return uval; // All characters were used, return the result + } + } + if (success_ptr) + *success_ptr = false; + return fail_value; +} + +uint64_t ToUInt64(const char *s, uint64_t fail_value, int base, + bool *success_ptr) { + if (s && s[0]) { + char *end = nullptr; + uint64_t uval = ::strtoull(s, &end, base); + if (*end == '\0') { + if (success_ptr) + *success_ptr = true; + return uval; // All characters were used, return the result + } + } + if (success_ptr) + *success_ptr = false; + return fail_value; +} + +double ToDouble(const char *s, double fail_value, bool *success_ptr) { + if (s && s[0]) { + char *end = nullptr; + double val = strtod(s, &end); + if (*end == '\0') { + if (success_ptr) + *success_ptr = true; + return val; // All characters were used, return the result + } + } + if (success_ptr) + *success_ptr = false; + return fail_value; +} +} +} -- cgit v1.2.3
