| * This is the first step in adding sane error handling support to LLVMSystem.Michael J. Spencer2010-11-164-0/+298
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The system API's will be shifted over to returning an error_code, and returning other return values as out parameters to the function. Code that needs to check error conditions will use the errc enum values which are the same as the posix_errno defines (EBADF, E2BIG, etc...), and are compatable with the error codes in WinError.h due to some magic in system_error. An example would be: if (error_code ec = KillEvil("Java")) { // error_code can be converted to bool. handle_error(ec); } git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119360 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | | | | | | | | | which contains slashes is inconsistent with the meaning of PATH on Unix-type platforms, and pretty surprising. If the user has given a specific path to execute and we can't execute it, we should fail and say why. (Apparently the new posix_spawn code doesn't always say why, but that's a separate issue.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@117596 91177308-0d34-0410-b5e6-96231b3b80d8
| * Revert r77396.Mikhail Glushenkov2010-10-281-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Original commit message: On "Unix", if Program::FindProgramByName is given a name containing slashes, just go with it, regardless of whether it looks like it will be executable. This follows the behavior of sh(1) more closely. It's better when behaviour is consistent between platforms. This change also makes FindExecutable() behave as expected on unix-likes (before this commit, it used to always succeed). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@117582 91177308-0d34-0410-b5e6-96231b3b80d8

| * Remove try/catch(...) from Win32/Signals.inc.Mikhail Glushenkov2010-10-272-11/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | catch(...) is used in Win32/Signals.inc for catching Win32 structured exceptions, but according to [1], this is wrong. We can't simply change try/catch to __try/__finally, since this syntax is not supported by MinGW. We can use __try/__finally on MSVC and __try1/__except1 macros on MinGW [2], but I think that that solution obfuscates the code too much. The use of try/catch(...) in Signals.inc makes it impossible to link MinGW-compiled libSystem with llvm-gcc compiled executables. I propose that we just remove try/catch(...) from Signals.inc, since the meaning of the code won't change.
