+Subject: [PATCH] fix x87 stack imbalance in corner cases of i386 math asm
+
+commit 31c5fb80b9eae86f801be4f46025bc6532a554c5 introduced underflow
+code paths for the i386 math asm, along with checks on the fpu status
+word to skip the underflow-generation instructions if the underflow
+flag was already raised. unfortunately, at least one such path, in
+log1p, returned with 2 items on the x87 stack rather than just 1 item
+for the return value. this is a violation of the ABI's calling
+convention, and could cause subsequent floating point code to produce
+NANs due to x87 stack overflow. if floating point results are used in
+flow control, this can lead to runaway wrong code execution.
+
+rather than reviewing each "underflow already raised" code path for
+correctness, remove them all. they're likely slower than just
+performing the underflow code unconditionally, and significantly more
+complex.
+
+all of this code should be ripped out and replaced by C source files
+with inline asm. doing so would preclude this kind of error by having
+the compiler perform all x87 stack register allocation and stack
+manipulation, and would produce comparable or better code. however
+such a change is a much larger project.
