| | | | | | | | | | | | that one of the numbers is signed while the other is unsigned. This could lead to a wrong result when the signed was promoted to an unsigned int. * Add the data layout line to the testcase so that it will test the appropriate thing. Patch by David Terei! llvm-svn: 128577

* Reset StringMap's NumTombstones on clears and rehashes.Jakob Stoklund Olesen2011-03-302-0/+6
| | | | | | | | | | | | | StringMap was not properly updating NumTombstones after a clear or rehash. This was not fatal until now because the table was growing faster than NumTombstones could, but with the previous change of preventing infinite growth of the table the invariant (NumItems + NumTombstones <= NumBuckets) stopped being observed, causing infinite loops in certain situations.

* Prevent infinite growth of the DenseMap.Jakob Stoklund Olesen2011-03-301-2/+5
| | | | | | | | | | | | | | | | | | When the hash function uses object pointers all free entries eventually become tombstones as they are used at least once, regardless of the size. DenseMap cannot function with zero empty keys, so it double size to get get ridof the tombstones. However DenseMap never shrinks automatically unless it is cleared, so the net result is that certain tables grow infinitely. The solution is to make a fresh copy of the table without tombstones instead of doubling size, by simply calling grow with the current size. Patch by José Fonseca! llvm-svn: 128564
* Many improvements to the Platform base class and subclasses. The base PlatformGreg Clayton2011-03-3074-1129/+3062
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | class now implements the Host functionality for a lot of things that make sense by default so that subclasses can check: int PlatformSubclass::Foo () { if (IsHost()) return Platform::Foo (); // Let the platform base class do the host specific stuff // Platform subclass specific code... int result = ... return result; } Added new functions to the platform: virtual const char *Platform::GetUserName (uint32_t uid); virtual const char *Platform::GetGroupName (uint32_t gid); The user and group names are cached locally so that remote platforms can avoid sending packets multiple times to resolve this information. Added the parent process ID to the ProcessInfo class. Added a new ProcessInfoMatch class which helps us to match processes up and changed the Host layer over to using this new class. The new class allows us to search for processs: 1 - by name (equal to, starts with, ends with, contains, and regex) 2 - by pid 3 - And further check for parent pid == value, uid == value, gid == value, euid == value, egid == value, arch == value, parent == value. This is all hookup up to the "platform process list" command which required adding dumping routines to dump process information. If the Host class implements the process lookup routines, you can now lists processes on your local machine: machine1.foo.com % lldb (lldb) platform process list PID PARENT USER GROUP EFF USER EFF GROUP TRIPLE NAME ====== ====== ========== ========== ========== ========== ======================== ============================ 99538 1 username usergroup username usergroup x86_64-apple-darwin FileMerge 94943 1 username usergroup username usergroup x86_64-apple-darwin mdworker 94852 244 username usergroup username usergroup x86_64-apple-darwin Safari 94727 244 username usergroup username usergroup x86_64-apple-darwin Xcode 92742 92710 username usergroup username usergroup i386-apple-darwin debugserver This of course also works remotely with the lldb-platform: machine1.foo.com % lldb-platform --listen 1234 machine2.foo.com % lldb (lldb) platform create remote-macosx Platform: remote-macosx Connected: no (lldb) platform connect connect://localhost:1444 Platform: remote-macosx Triple: x86_64-apple-darwin OS Version: 10.6.7 (10J869) Kernel: Darwin Kernel Version 10.7.0: Sat Jan 29 15:17:16 PST 2011; root:xnu-1504.9.37~1/RELEASE_I386 Hostname: machine1.foo.com Connected: yes (lldb) platform process list PID PARENT USER GROUP EFF USER EFF GROUP TRIPLE NAME ====== ====== ========== ========== ========== ========== ======================== ============================ 99556 244 username usergroup username usergroup x86_64-apple-darwin trustevaluation 99548 65539 username usergroup username usergroup x86_64-apple-darwin lldb 99538 1 username usergroup username usergroup x86_64-apple-darwin FileMerge 94943 1 username usergroup username usergroup x86_64-apple-darwin mdworker 94852 244 username usergroup username usergroup x86_64-apple-darwin Safari The lldb-platform implements everything with the Host:: layer, so this should "just work" for linux. I will probably be adding more stuff to the Host layer for launching processes and attaching to processes so that this support should eventually just work as well. Modified the target to be able to be created with an architecture that differs from the main executable. This is needed for iOS debugging since we can have an "armv6" binary which can run on an "armv7" machine, so we want to be able to do: % lldb (lldb) platform create remote-ios (lldb) file --arch armv7 a.out Where "a.out" is an armv6 executable. The platform then can correctly decide to open all "armv7" images for all dependent shared libraries. Modified the disassembly to show the current PC value. Example output: (lldb) disassemble --frame a.out`main: 0x1eb7: pushl %ebp 0x1eb8: movl %esp, %ebp 0x1eba: pushl %ebx 0x1ebb: subl $20, %esp 0x1ebe: calll 0x1ec3 ; main + 12 at test.c:18 0x1ec3: popl %ebx -> 0x1ec4: calll 0x1f12 ; getpid 0x1ec9: movl %eax, 4(%esp) 0x1ecd: leal 199(%ebx), %eax 0x1ed3: movl %eax, (%esp) 0x1ed6: calll 0x1f18 ; printf 0x1edb: leal 213(%ebx), %eax 0x1ee1: movl %eax, (%esp) 0x1ee4: calll 0x1f1e ; puts 0x1ee9: calll 0x1f0c ; getchar 0x1eee: movl $20, (%esp) 0x1ef5: calll 0x1e6a ; sleep_loop at test.c:6 0x1efa: movl $12, %eax 0x1eff: addl $20, %esp 0x1f02: popl %ebx 0x1f03: leave 0x1f04: ret This can be handy when dealing with the new --line options that was recently added: (lldb) disassemble --line a.out`main + 13 at test.c:19 18 { -> 19 printf("Process: %i\n\n", getpid()); 20 puts("Press any key to continue..."); getchar(); -> 0x1ec4: calll 0x1f12 ; getpid 0x1ec9: movl %eax, 4(%esp) 0x1ecd: leal 199(%ebx), %eax 0x1ed3: movl %eax, (%esp) 0x1ed6: calll 0x1f18 ; printf Modified the ModuleList to have a lookup based solely on a UUID. Since the UUID is typically the MD5 checksum of a binary image, there is no need to give the path and architecture when searching for a pre-existing image in an image list. Now that we support remote debugging a bit better, our lldb_private::Module needs to be able to track what the original path for file was as the platform knows it, as well as where the file is locally. The module has the two following functions to retrieve both paths: const FileSpec &Module::GetFileSpec () const; const FileSpec &Module::GetPlatformFileSpec () const; llvm-svn: 128563
* Fix evil VirtRegRewriter bug.Jakob Stoklund Olesen2011-03-301-0/+28
| | | | | | | | | | | | | | | The rewriter can keep track of multiple stack slots in the same register if they happen to have the same value. When an instruction modifies a stack slot by defining a register that is mapped to a stack slot, other stack slots in that register are no longer valid. This is a very rare problem, and I don't have a simple test case. I get the impression that VirtRegRewriter knows it is about to be deleted, inventing a last opaque problem. <rdar://problem/9204040> llvm-svn: 128562

* elf: synthesize symbols for PLT entriesStephen Wilson2011-03-302-50/+463
| | | | | | | | | | | When populating symbol tables ObjectFileELF now generates a set of synthetic trampoline symbols. These new symbols correspond to entries in the program linkage table and have a (possibly mangled) name identifying the corresponding symbol in some DSO. These symbols will be used by the DynamicLoader loader plugin on Linux to provide thread plans when execution flows from one DSO to another. llvm-svn: 128550

* Add APFloat::getExactInverse.Benjamin Kramer2011-03-303-0/+53
| | | | | | | | | | | | | | The idea is, that if an ieee 754 float is divided by a power of two, we can turn the division into a cheaper multiplication. This function sees if we can get an exact multiplicative inverse for a divisor and returns it if possible. This is the hard part of PR9587. I tested many inputs against llvm-gcc's frotend implementation of this optimization and didn't find any difference. However, floating point is the land of weird edge cases, so any review would be appreciated. llvm-svn: 128545
