From 04bbbba271ebe4c2421f34a4fbf34c328df9f111 Mon Sep 17 00:00:00 2001 From: Jason Molenda Date: Wed, 6 Mar 2024 10:53:37 -0800 Subject: Skip TestAddressMasks API tests on 32-bit arm TestAddressMasks failed on the lldb-arm-buntu bot with the Code address mask test, mask = process.GetAddressMask(lldb.eAddressMaskTypeAny) process.SetAddressMask(lldb.eAddressMaskTypeCode, mask | 0x3) self.assertEqual( 0x000002950001F694, process.FixAddress(0x00265E950001F697, lldb.eAddressMaskTypeCode), ) The API returned 0x000002950001f694 instead of the expected 0x00265e950001f696. The low bits differ because ABISysV_arm hardcodes the Code address mask to clear the 0th bit, it doesn't use the Process code mask. I didn't debug why some of the high bytes were dropped. The address mask APIs are only important on 64-bit targets, where many of the bits are not used for addressing and are used for metadata instead, so I'm going to skip these tests on 32-bit arm instead of debugging. --- lldb/test/API/python_api/process/address-masks/TestAddressMasks.py | 3 +++ 1 file changed, 3 insertions(+) (limited to 'lldb/test/API/python_api') diff --git a/lldb/test/API/python_api/process/address-masks/TestAddressMasks.py b/lldb/test/API/python_api/process/address-masks/TestAddressMasks.py index e0a570c..152776efc 100644 --- a/lldb/test/API/python_api/process/address-masks/TestAddressMasks.py +++ b/lldb/test/API/python_api/process/address-masks/TestAddressMasks.py @@ -19,6 +19,7 @@ class AddressMasksTestCase(TestBase): self.runCmd("settings set target.process.virtual-addressable-bits 0") self.runCmd("settings set target.process.highmem-virtual-addressable-bits 0") + @skipIf(archs=["arm"]) # 32-bit arm ABI hardcodes Code mask, is 32-bit def test_address_masks(self): self.build() (target, process, t, bp) = lldbutil.run_to_source_breakpoint( @@ -79,6 +80,7 @@ class AddressMasksTestCase(TestBase): # AArch64 can have different address masks for high and low memory, when different # page tables are set up. @skipIf(archs=no_match(["arm64", "arm64e", "aarch64"])) + @skipIf(archs=["arm"]) # 32-bit arm ABI hardcodes Code mask, is 32-bit def test_address_masks_target_supports_highmem_tests(self): self.build() (target, process, t, bp) = lldbutil.run_to_source_breakpoint( @@ -111,6 +113,7 @@ class AddressMasksTestCase(TestBase): # On most targets where we have a single mask for all address range, confirm # that the high memory masks are ignored. @skipIf(archs=["arm64", "arm64e", "aarch64"]) + @skipIf(archs=["arm"]) # 32-bit arm ABI hardcodes Code mask, is 32-bit def test_address_masks_target_no_highmem(self): self.build() (target, process, t, bp) = lldbutil.run_to_source_breakpoint( -- cgit v1.1
