+# Ascetic x86_64 AT&T to MASM assembler translator by <appro>.
+#
+# Why AT&T to MASM and not vice versa? Several reasons. Because AT&T
+# format is way easier to parse. Because it's simpler to "gear" from
+# Unix ABI to Windows one [see cross-reference "card" at the end of
+# file]. Because Linux targets were available first...
+#
+# In addition the script also "distills" code suitable for GNU
+# assembler, so that it can be compiled with more rigid assemblers,
+# such as Solaris /usr/ccs/bin/as.
+#
+# This translator is not designed to convert *arbitrary* assembler
+# code from AT&T format to MASM one. It's designed to convert just
+# enough to provide for dual-ABI OpenSSL modules development...
+# There *are* limitations and you might have to modify your assembler
+# code or this script to achieve the desired result...
+#
+# Currently recognized limitations:
+#
+# - can't use multiple ops per line;
+# - indirect calls and jumps are not supported;
+#
+# Dual-ABI styling rules.
+#
+# 1. Adhere to Unix register and stack layout [see the end for
+# explanation].
+# 2. Forget about "red zone," stick to more traditional blended
+# stack frame allocation. If volatile storage is actually required
+# that is. If not, just leave the stack as is.
+# 3. Functions tagged with ".type name,@function" get crafted with
+# unified Win64 prologue and epilogue automatically. If you want
+# to take care of ABI differences yourself, tag functions as
+# ".type name,@abi-omnipotent" instead.
+# 4. To optimize the Win64 prologue you can specify number of input
+# arguments as ".type name,@function,N." Keep in mind that if N is
+# larger than 6, then you *have to* write "abi-omnipotent" code,
+# because >6 cases can't be addressed with unified prologue.
+# 5. Name local labels as .L*, do *not* use dynamic labels such as 1:
+# (sorry about latter).
+# 6. Don't use [or hand-code with .byte] "rep ret." "ret" mnemonic is
+# required to identify the spots, where to inject Win64 epilogue!
+# But on the pros, it's then prefixed with rep automatically:-)
+# 7. Due to MASM limitations [and certain general counter-intuitivity
+# of ip-relative addressing] generation of position-independent
+# code is assisted by synthetic directive, .picmeup, which puts
+# address of the *next* instruction into target register.
+#
+# Example 1:
+# .picmeup %rax
+# lea .Label-.(%rax),%rax
+# Example 2:
+# .picmeup %rcx
+# .Lpic_point:
+# ...
+# lea .Label-.Lpic_point(%rcx),%rbp
