b7cef81f - Replace "no-frame-pointer-*" function attributes with "frame-pointer"

Mon, 14 Jan 2019 10:55:55 +0000

Replace "no-frame-pointer-*" function attributes with "frame-pointer"Part of the effort to refactoring frame pointer code generation. We usedto use two function attributes "no-frame-pointer-elim" and"no-frame-pointer-elim-non-leaf" to represent three kinds of framepointer usage: (all) frames use frame pointer, (non-leaf) frames useframe pointer, (none) frame use frame pointer. This CL makes the ideaexplicit by using only one enum function attribute "frame-pointer"Option "-frame-pointer=" replaces "-disable-fp-elim" for tools such asllc."no-frame-pointer-elim" and "no-frame-pointer-elim-non-leaf" are stillsupported for easy migration to "frame-pointer".tests are mostly updated with// replace command line args ‘-disable-fp-elim=false’ with ‘-frame-pointer=none’grep -iIrnl '\-disable-fp-elim=false' * | xargs sed -i '' -e "s/-disable-fp-elim=false/-frame-pointer=none/g"// replace command line args ‘-disable-fp-elim’ with ‘-frame-pointer=all’grep -iIrnl '\-disable-fp-elim' * | xargs sed -i '' -e "s/-disable-fp-elim/-frame-pointer=all/g"Patch by Yuanfang Chen (tabloid.adroit)!Differential Revision: https://reviews.llvm.org/D56351llvm-svn: 351049 List of files: /llvm-project-15.0.7/llvm/test/CodeGen/ARM/hello.ll

9aa6f010 - [ARM] Generate consistent frame records for Thumb2

Tue, 23 Aug 2016 09:19:22 +0000

[ARM] Generate consistent frame records for Thumb2There is not an official documented ABI for frame pointers in Thumb2,but we should try to emit something which is useful.We use r7 as the frame pointer for Thumb code, which currently meansthat if a function needs to save a high register (r8-r11), it will getpushed to the stack between the frame pointer (r7) and link register(r14). This means that while a stack unwinder can follow the chain offrame pointers up the stack, it cannot know the offset to lr, so doesnot know which functions correspond to the stack frames.To fix this, we need to push the callee-saved registers in two batches,with the first push saving the low registers, fp and lr, and the secondpush saving the high registers. This is already implemented, butpreviously only used for iOS. This patch turns it on for all Thumb2targets when frame pointers are required by the ABI, and the framepointer is r7 (Windows uses r11, so this isn't a problem there). Ifframe pointer elimination is enabled we still emit a single push/popeven if we need a frame pointer for other reasons, to avoid increasingcode size.We must also ensure that lr is pushed to the stack when using a framepointer, so that we end up with a complete frame record. Situations thatcould cause this were rare, because we already push lr in mostsituations so that we can return using the pop instruction.Differential Revision: https://reviews.llvm.org/D23516llvm-svn: 279506 List of files: /llvm-project-15.0.7/llvm/test/CodeGen/ARM/hello.ll

7258735f - ARM: fixup more tests to specify the target more explicitly

Thu, 03 Apr 2014 16:01:44 +0000

ARM: fixup more tests to specify the target more explicitlyThis changes the tests that were targeting ARM EABI to explicitly specify theenvironment rather than relying on the default. This breaks with the newWindows on ARM support when running the tests on Windows where the defaultenvironment is no longer EABI.Take the opportunity to avoid a pointless redirect (helps when trying to debugwith providing a command line invocation which can be copy and pasted) andremoving a few greps in favour of FileCheck.llvm-svn: 205541 List of files: /llvm-project-15.0.7/llvm/test/CodeGen/ARM/hello.ll

Fix epilogue codegen to avoid leaving the stack pointer in an invalidstate. Previously Thumb2 would restore sp from fp like this:mov sp, r7sub, sp, #4If an interrupt is taken after the 'mov' but before the 'sub', callee-savedregisters might be clobbered by the interrupt handler. Instead, tryrestoring directly from sp:add sp, #4Or, if necessary (with VLA, etc.) use a scratch register to compute sp andthen restore it:sub.w r4, r7, #8mov sp, r7rdar://8465407llvm-svn: 119977 List of files: /llvm-project-15.0.7/llvm/test/CodeGen/ARM/hello.ll
