Bug ID: 45014
Summary: interception_type_test fails for Android API >= 24
32-bit
Product: compiler-rt
Version: unspecified
Hardware: PC
OS: All
Status: NEW
Severity: enhancement
Priority: P
Component: compiler-rt

sets -D_FILE_OFFSET_BITS=64 for Android when targeting API level >= 24, which
means we get a 64-bit off_t even on 32-bit targets. However, compiler-rt
defines its OFF_T type for 32-bit Android as 32 bits in
https://github.com/llvm/llvm-project/blob/2c0edbf19c1b0115b944cd017201eaf1f6a832ee/compiler-rt/lib/sanitizer_common/sanitizer_internal_defs.h#L178.
interception_type_test.cpp then unconditionally compares the sizes of off_t and
OFF_T for Android in
https://github.com/llvm/llvm-project/blob/2c0edbf19c1b0115b944cd017201eaf1f6a832ee/compiler-rt/lib/interception/interception_type_test.cpp#L36,
which of course fails.
Should we adjust OFF_T to be 64 bits on Android APIs >= 24?
