- /// ensures that the path it encapsulates is syntactically valid for the
- /// operating system it is running on but does not ensure correctness for
- /// any particular file system. That is, a syntactically valid path might
- /// specify path components that do not exist in the file system and using
- /// such a Path to act on the file system could produce errors. There is one
- /// invalid Path value which is permitted: the empty path. The class should

- /// invalid path name (in which case the Path object is left unchanged) or

+Design Of lib/System
+====================
+
+The software in this directory is designed to completely shield LLVM from any
+and all operating system specific functionality. It is not intended to be a
+complete operating system wrapper (such as ACE), but only to provide the
+functionality necessary to support LLVM.
+
+The software located here, of necessity, has very specific and stringent design
+rules. Violation of these rules means that cracks in the shield could form and
+the primary goal of the library is defeated. By consistently using this library,
+LLVM becomes more easily ported to new platforms since the only thing requiring
+porting is this library.
+
+Complete documentation for the library can be found in the file:
+ llvm/docs/SystemLibrary.html
+or at this URL:
+ http://llvm.org/docs/SystemLibrary.html
+
+While we recommend that you read the more detailed documentation, for the
+impatient, here's a high level summary of the library's requirements.
+
+ 1. No system header files are to be exposed through the interface.
+ 2. Std C++ and Std C header files are okay to be exposed through the interface.
+ 3. No exposed system-specific functions.
+ 4. No exposed system-specific data.
+ 5. Data in lib/System classes must use only simple C++ intrinsic types.
+ 6. Errors are handled by returning "true" and setting an optional std::string
+ 7. Library must not throw any exceptions, period.
+ 8. Interface functions must not have throw() specifications.
+ 9. No duplicate function impementations are permitted within an operating
+ system class.
+
+To accomplish these requirements, the library has numerous design criteria that
+must be satisfied. Here's a high level summary of the library's design criteria:
+
+ 1. No unused functionality (only what LLVM needs)
+ 2. High-Level Interfaces
+ 3. Use Opaque Classes
+ 4. Common Implementations
+ 5. Multiple Implementations
+ 6. Minimize Memory Allocation
+ 7. No Virtual Methods

+llvm/lib/Support/Unix README
+===========================
+
+This directory provides implementations of the lib/System classes that
+are common to two or more variants of UNIX. For example, the directory
+structure underneath this directory could look like this:
+
+Unix - only code that is truly generic to all UNIX platforms
+ Posix - code that is specific to Posix variants of UNIX
+ SUS - code that is specific to the Single Unix Specification
+ SysV - code that is specific to System V variants of UNIX
+
+As a rule, only those directories actually needing to be created should be
+created. Also, further subdirectories could be created to reflect versions of
+the various standards. For example, under SUS there could be v1, v2, and v3
+subdirectories to reflect the three major versions of SUS.

-Design Of lib/System
-====================
-
-The software in this directory is designed to completely shield LLVM from any
-and all operating system specific functionality. It is not intended to be a
-complete operating system wrapper (such as ACE), but only to provide the
-functionality necessary to support LLVM.
-
-The software located here, of necessity, has very specific and stringent design
-rules. Violation of these rules means that cracks in the shield could form and
-the primary goal of the library is defeated. By consistently using this library,
-LLVM becomes more easily ported to new platforms since the only thing requiring
-porting is this library.
-
-Complete documentation for the library can be found in the file:
- llvm/docs/SystemLibrary.html
-or at this URL:
- http://llvm.org/docs/SystemLibrary.html
-
-While we recommend that you read the more detailed documentation, for the
-impatient, here's a high level summary of the library's requirements.
-
- 1. No system header files are to be exposed through the interface.
- 2. Std C++ and Std C header files are okay to be exposed through the interface.
- 3. No exposed system-specific functions.
- 4. No exposed system-specific data.
- 5. Data in lib/System classes must use only simple C++ intrinsic types.
- 6. Errors are handled by returning "true" and setting an optional std::string
- 7. Library must not throw any exceptions, period.
- 8. Interface functions must not have throw() specifications.
- 9. No duplicate function impementations are permitted within an operating
- system class.
-
-To accomplish these requirements, the library has numerous design criteria that
-must be satisfied. Here's a high level summary of the library's design criteria:
-
- 1. No unused functionality (only what LLVM needs)
- 2. High-Level Interfaces
- 3. Use Opaque Classes
- 4. Common Implementations</a></li>
- 5. Multiple Implementations</a></li>
- 6. Minimize Memory Allocation</a></li>
- 7. No Virtual Methods

-===========================
-
-This directory provides implementations of the lib/System classes that
-are common to two or more variants of UNIX. For example, the directory
-structure underneath this directory could look like this:
-
-Unix - only code that is truly generic to all UNIX platforms
- Posix - code that is specific to Posix variants of UNIX
- SUS - code that is specific to the Single Unix Specification
- SysV - code that is specific to System V variants of UNIX
-
-As a rule, only those directories actually needing to be created should be
-created. Also, further subdirectories could be created to reflect versions of
-the various standards. For example, under SUS there could be v1, v2, and v3
-subdirectories to reflect the three major versions of SUS.
