On aarch64-linux, with gcc 7.5.0, we run into: ... (gdb) frame^M #0 callee.increment (val=99.0, val@entry=9.18340949e-41, msg=...) at \ callee.adb:21^M 21 if Val > 200.0 then^M (gdb) FAIL: gdb.ada/O2_float_param.exp: scenario=all: frame ... The problem is a GCC bug, filed as "PR98148 - [AArch64] Wrong location expression for function entry values" ( https://gcc.gnu.org/bugzilla/show_bug.cgi?id=98148 ). Xfail the test for aarch64 and gcc 7. Tested on x86_64-linux and aarch64-linux. Bug: https://sourceware.org/bugzilla/show_bug.cgi?id=29418
